U-turns can be a convenient way to change direction when you’re driving on the road, but only when they’re made safely in the right place and at the right time.
To help keep everyone in our community safe, it’s important to know where U-turns are permitted in Halton and how to make them properly while sharing the road with other drivers, cyclists and pedestrians.
What is a U-turn and where can you make one in Halton?
A U-turn is a driving manoeuvre in which a driver turns their vehicle around in a 180-degree rotation to travel in the opposite direction, forming a path shaped like the letter "U".
In Halton, a U-turn is a legal driving manoeuvre unless prohibited by ‘No U-turn' signage.
When there is a U-turn restriction, it’s important to note that it may only apply to one direction of travel. This means that a U-turn could be prohibited for drivers approaching an intersection from one direction but permitted for drivers approaching from another. Always pay close attention to posted signage for your direction of travel.
Where are U-turns prohibited?
Under Ontario’s Highway Traffic Act (external link), U-turns are prohibited:
- where there is a "No U-turn" sign
- in areas with limited visibility, such on or near curves, hills, bridges, viaducts or tunnels, where drivers cannot see at least 150 metres away in both directions
- on or within 30 metres of a railway crossing
Before making a U-turn, always check for posted signage and ensure you have a clear view of traffic in both directions.
When should you still avoid a U-turn?
Although U-turns are legal unless otherwise prohibited, drivers are responsible for ensuring they can be completed safely. You should avoid making a U-turn when:
- traffic is heavy
- your visibility is limited
- you are not certain how other road users will react
- there is not enough room to safely complete the turn
- other drivers, pedestrians or cyclists may be affected by the turn
How to make a safe U-turn: A 5-step safety check
Before making a U-turn, ask yourself these five questions to help ensure the manoeuvre can be completed safely.
1. Is a U-turn allowed?
Before making a U-turn, check for any restrictions, including:
- ‘No U-turn' signs
- other regulatory signs
- road markings that may restrict turning movements.
If a U-turn is prohibited, choose another route.
2. Can I clearly see approaching traffic?
Visibility is essential! Make sure you can clearly see:
- vehicles approaching from both directions
- vehicles that may be turning
- pedestrians crossing the road
- cyclists and other road users
If your view is blocked or visibility is limited, do not attempt the U-turn. Wait for conditions to improve or continue to another location.
3. Is there a safe gap in traffic?
Do not assume other drivers are expecting you to make a U-turn. Wait until there is enough time and space to complete the turn safely without affecting other road users.
A good rule to follow: Never force a U-turn.
4. Have I signaled my intention?
Always signal well in advance. Before turning:
- check your mirrors and blindspots
- signal your intent
- reassess traffic conditions
Clear communication helps other road users understand what you’re about to do.
5. Can I complete the U-turn carefully and with control?
Know your vehicle’s turning radius and the space needed to safely complete the U-turn. When making the turn, you should never:
- mount the curb
- enter pedestrian areas
- make an unsafe multi-point turn
- cut off approaching traffic
As you complete the U-turn, continue scanning for pedestrians, cyclists and vehicles.
Are there penalties for illegal or unsafe U-turns?
The simple answer is yes. Penalties for illegal or unsafe U-turns are enforced by Halton Regional Police and can result in:
- a fine
- two demerit points for a prohibited turn conviction
If an illegal or unsafe U-turn contributes to a collision, additional charges could apply depending on the circumstance. Before making a U-turn, always ensure the manoeuvre is legal and safe.
U-turns and Regional roads
Some intersections on Regional roads have specific U-turn restrictions based on safety and operational reviews performed by Halton Region staff. These restrictions are established through Schedule 16 – U-Turns of Halton Region Traffic By-law No. 1984-1.
At other Regional intersections, U-turns are specifically permitted and may be controlled by traffic signals. Our location-specific approach to U-turns focuses on:
- allowing the manoeuvre where road conditions support the movement
- restricting the manoeuvre where safety and operational concerns have been identified.
Remember! U-turn restrictions may apply to only one direction of travel. Always check and follow the posted signs for the direction you are travelling.
Have a U-turn concern?
When concerns are raised about U-turns on Regional Roads, Halton Region staff can conduct a safety and operational review. These reviews may consider factors such as collision history, visibility and sightlines, traffic volumes, roadway and intersection design. Staff may also evaluate potential conflicts with other drivers, cyclists and pedestrians.
