In some cases, where lanes are changed at particular times of the day, for instance in peak hours, overhead warningsigns are used. A red cross is used to tell you the lane is closed, a green arrow tells you it is open to traffic.
Also included in the sign are the days and the time of day the transit lanes are used. It’s usually weekdays, either in the morning or afternoon.
To aid traffic flow on freeways or motorways at peak times lanes can be dedicated to cars carrying three or more occupants.
It is rectangular, with the words ‘KEEP LEFT’ and an arrow pointing to the left in black on a white background with a black border.
PIP (3:1) is used as a plasticizer, a flame retardant, an anti-wear additive, or an anti-compressibility additive in hydraulic fluid, lubricating oils, lubricants and greases, various industrial coatings, adhesives, sealants, and plastic articles. As a chemical that can perform several functions simultaneously, sometimes under extreme conditions, it has several distinctive applications. Learn more about PIP (3:1) uses. Identified Hazards – PIP (3:1) is toxic to aquatic plants, aquatic invertebrates, sediment invertebrates and fish. Data indicate the potential for reproductive and developmental effects, neurological effects and effects on systemic organs, specifically adrenals, liver, ovary, heart, and lungs.
They are diamond shaped, with a black graphic illustrating the hazard on a yellow background, and could warn you of a blind crest, a dip, a steep descent, a T-intersection, traffic lights, a tight curve, a narrow bridge, a road hump, a pedestrian crossing, or a tricky series of bends.
In May 2018, EPA conducted letter peer reviews of exposure and hazard information for the five PBT chemicals selected for expedited review under the amended TSCA. EPA also accepted written comments on the charge questions and other documents to be considered by the peer reviewers. These materials are available in docket EPA-HQ-OPPT-2018-0314.
To make a right turn at the intersections where HOOK TURNS are required you must drive into the intersection in the left lane indicating your intention to turn right and then come to a halt and wait until through traffic clears when you can safely complete the turn.
On December 12, 2024 at 2pm ET EPA will host a public webinar on the 2024 final rule for decaBDE and PIP (3:1). During this webinar, EPA will present an overview of the final rule and respond to inquiries that have been submitted in advance.
In some cases turns are only banned at certain times of the day. When that is the case the sign also has the times when the turn in banned.
The signs denoting a transit lane are white with the words Transit Lane in black above an indicator of the number of occupants needed before you can use the transit lane in white on a red background.
In some situations turns are banned for safety and to facilitate traffic flow. They could be left turns, right turns, or U-turns.
If there was an award for the most confusing road signs in Australia it world have to go to Melbourne’s so-called ‘HOOK TURNS’ at a number of intersections in the city CBD and require right turns to be made from the left lane so the flow of trams isn’t impeded through the intersection.
On September 7, 2017 EPA hosted a webinar, “Use Information for Persistent, Bioaccumulative, and Toxic (PBT) Chemicals Under TSCA Section 6(h).” This webinar provided background on the requirements for PBT chemicals under amended TSCA and explained to interested parties the process for gathering use and exposure information the five PBT chemicals.
Additionally, EPA established public dockets for each of the five PBT chemicals to facilitate receipt of information on exposure and use which may be useful to the Agency’s rulemaking effort. To read the comments EPA received, visit the docket for each chemical.
Parking can also be banned in areas limited for business use, such as a LOADING ZONE, BUS ZONE, TAXI ZONE, or a zone that requires a permit.
They are mostly yellow and black, but could be orange and black, or could be a red triangle if it’s an incident on the road.
EPA prohibited the manufacturing (including import), processing, and distribution in commerce of HCBD and HCBD-containing products or articles, except for the unintentional production of HCBD as a byproduct during the production of chlorinated solvents, and the processing and distribution in commerce of HCBD for burning as a waste fuel.
In October 2024 EPA published a final rule revising existing rules for decaBDE and PIP (3:1). This final rule requires workplace safety protections reducing exposure to those who work with those chemicals to the extent practicable, sets a limit for their concentrations in products and articles, and further prohibits water releases. It also addresses broader implementation issues affecting the supply chains of various industry sectors including the nuclear energy, transportation, construction, agriculture, forestry, mining, life sciences, and semiconductor production sectors by revising compliance dates for certain uses of the chemicals.
It is rectangular with the letter ‘S’ in black inside a red circle crossed by a diagonal red line on a white background. A red arrow will point to the affected area.
School zone zones can be square or rectangular in shape with sections indicating the speed limit, which is shown in black inside a red circle on a white background, together with the times and days the speed limit applies, also black on a white background, and headed by a yellow ‘SCHOOL ZONE’ warning in black on a yellow background.
DecaBDE is used as an additive flame retardant in plastic enclosures for televisions, computers, audio and video equipment, textiles and upholstered articles, wire and cables for communication and electronic equipment, and other applications. DecaBDE is also used as a flame retardant for multiple applications for aerospace and automotive vehicles, including replacement parts for aircraft and cars. Learn more about decaBDE uses.
The sign telling you that a roundabout is coming up is triangular in shape with three black arrows forming a circle in a clockwise direction inside a red triangle on a white background.

EPA also established public dockets for public comment on the March 2021 notice requesting input on the five PBT rules :EPA-HQ-OPPT-2021-0202.
The ‘TWO WAY’ sign tells you that you are driving on a two-way road and traffic will be coming at you from the other direction in the right hand lane.
Speed advisory signs telling you of the maximum safe speed you can expect to negotiate a sign-posted curve are also commonly used.

HOOK TURNS are indicated by a rectangular sign with a directional arrow and the words ‘RIGHT TURN FROM LEFT ONLY’ in black on a white background with a black border.
Street signs and place names are the most stolen signs in Australia, usually because they have a common connection to something else in the community. Signs including ‘Monaro’ are some of the most stolen.
Road signs are used to bring order to our roads so that we can go about our business in relative safety with minimum delay. Without them chaos would reign and our daily drive would be rather more dangerous.

They’re white with the word CLEARWAY in black, as well as the letter ‘C’ in a red box, and the days and times the Clearway is in use.
A ‘ONE WAY’ sign is square with the words ONE WAY and an arrow in the direction of the permitted traffic flow in black on a white background with a black border.
Road signs in Australia are a state responsibility, but they conform to national guidelines, so that are in effect the same right across the country.
Temporary warning signs are erected to warn drivers they are approaching a hazard that is currently requiring extra caution.
These signs are rectangular with a white background and a red box in which the particular use of the zone is show in white.
Identified Hazards – 2,4,6-TTBP is toxic to aquatic plants, aquatic invertebrates, and fish. Surveyed animal data indicate the potential for liver and developmental effects.
Secure .gov websites use HTTPS A lock (LockA locked padlock) or https:// means you’ve safely connected to the .gov website. Share sensitive information only on official, secure websites.
It is rectangular, with a white dash inside a red circle above the words ‘NO ENTRY’ in black on a white background with a black border.
EPA prohibited the distribution in commerce of 2,4,6-TTBP and products containing 2,4,6-TTBP at concentrations above 0.3% by weight in any container with a volume of less than 35 gallons in order to effectively prevent the use of 2,4,6-TTBP as a fuel additive or fuel injector cleaner by consumers and small commercial operations (e.g., automotive repair shops, marinas).
Warning signs are there to warn you of an upcoming hazard requiring caution. When facing a warning sign, the message is clear, take care.
In some case the parking ban only applies on certain days and at certain times, and these will be spelt out on the sign.
For the safety of workers temporary signs indicating reduced speed limits are posted at sites where roadworks are taking place.
In some cases the parking limitations only apply for certain times on particular days, and that information will also be shown on the sign.

Do not enter a street or road when you see a ‘NO ENTRY’ sign. It is most likely a one-way street and you would be going against the traffic flow.
The Frank R. Lautenberg Chemical Safety for the 21st Century Act, enacted on June 22, 2016, includes a provision under TSCA section 6(h) requiring EPA to take expedited action on specific PBT chemicals to address risk and reduce exposures to the extent practicable. Pursuant to the statute, no risk evaluation is required for these chemicals.
With the overall consistency of signs throughout the country we can feel confident to drive anywhere in the country and still recognise and understand the traffic signs in use.
The fixed school zone signs are often accompanied by flashing speed signs, with the speed limit in white inside a flashing red circle.
Parking signs are also designed to aid traffic flow and to give everyone fair access to a parking spot when they need it, albeit for a limited time.

At the same time the states and local councils can use signs that relate to particular situations in their areas, and you need to be alert to them. Even when local bodies erect signs they still follow the general theme of the national guidelines.
Warning signs are also displayed at locations where traffic has to merge, say from three lanes to two, or two to one. The graphic will show an arrow/arrows continuing on where traffic is unaffected, and one coming to a dead end where you have to merge in to an adjacent lane.

EPA published a rule addressing PIP (3:1) in 2021, with revisions and additional requirements published in 2022 and 2024:
The final PBT rule addresses implementation issues raised by the 2021 PIP (3:1) rule and its subsequent revisions associated with the October 31, 2024 compliance deadline for processing and distributing PIP (3:1) for use in articles and PIP (3:1)-containing articles. The final rule amends phase-in prohibitions and exclusions on processing and distribution for certain uses and further extends the compliance dates for some articles used in heating, ventilation, air-conditioning, refrigeration, and water-heating equipment, power generating equipment, laboratory equipment, commercial electronic equipment, and manufacturing equipment, including manufacturing equipment used in the semiconductor industry. EPA is not revising the October 2024 compliance date for articles not otherwise covered by (1) an exclusion from prohibition or (2) an existing or newly finalized extension to a phase-out compliance deadline. The amended phase-in prohibitions and exclusions are effective 60 days after the final rule is published in the Federal Register. EPA intends to focus its enforcement on ensuring compliance with the requirements of this final rule.
The signs indicating a particular turn is banned are rectangular with a black arrow in the direction of the banned turn inside a red circle on a white background.
As required under section 6(h) of the Toxic Substances Control Act (TSCA), as amended by the Frank R. Lautenberg Chemical Safety for the 21st Century Act, EPA has taken action to reduce exposures to certain chemicals that are persistent, bioaccumulative and toxic (PBT). These chemicals build up in the environment over time and can therefore have potential risks for exposed populations, including the general population, consumers and commercial users, and susceptible subpopulations (such as workers, subsistence fishers, tribes and children). In October 2024, EPA issued a final rule amending the rules for decabromodiphenyl (decaBDE) and phenol, isopropylated phosphate (3:1) PIP (3:1).

2,4,6-TTBP is used as an intermediate/reactant in processing and is incorporated into formulations destined for fuel and fuel-related additives, as well as into formulations intended for the maintenance or repair of motor vehicles and machinery, including in oils and lubricants. Learn more about 2,4,6-TTBP uses.
On December 14, 2023 EPA hosted a public webinar on the 2023 proposed rule for decaBDE and PIP (3:1). During this webinar, EPA presented an overview of the proposed rule and received public comments to inform the development of the 2024 final rule.
On September 27, 2024, as a bridge to the final rule effective date, EPA extended its May 2, 2023, temporary Enforcement Statement of decaBDE. Learn more about the Enforcement Statement for DecaBDE:
It is a rectangular sign with a ‘P’ in black inside a red circle with a diagonal red line through the ‘P’ on a white background. It also has an arrow indicating the area of the parking ban.
The sign often includes an illustration of a tow truck removing an illegally parked car to graphically show the consequences of not obeying the restriction.
They might point you in the right direction, tell you how far you are from your destination, tell you what road or highway you are on, and the name of the street you are seeking.
They apply at specified times during the day, usually between 8 am and 9.30 am when students are arriving in the morning and 2.30 pm and 4 pm when they’re leaving at the end of the school day.
Parking signs are rectangular, either vertical or horizontal, with the time permitted to park, for instance 2P for parking permitted for two hours, in green on a white background.
