Driving safely in road work zones

In and around road work zones, lane configurations can change at any time, forcing you to drive in a reduced lane, change lanes or take a detour. To make your driving more enjoyable and safer, it’s essential to adopt safe habits to reduce the risk of accidents and help improve the safety of workers and other road users.

Seven safe habits to adopt when driving

Driving habits every driver should practice:

  1. Focus your attention on the road (avoid distractions).
  2. Obey all road work signs.
  3. Stick to the posted speed limits.
  4. Keep a safe distance between your vehicle and the one ahead of you.
  5. Follow the flag person’s instructions.
  6. Respect the traffic control barrier (flag person’s barrier) or temporary lights.
  7. Use the late merge (zipper merge) strategy to keep traffic moving.

Check for traffic obstructions before hitting the road

Every year, a large number of road construction, repair and maintenance projects are carried out. These projects may have a significant impact on your travel plans. Plan your trips and regularly check for updates on road work underway on the Ministère’s transport network at

Fines double for speeding in road work zones

If you exceed the posted speed limit in a road work zone, you risk being fined twice as much as elsewhere on the road.

Disobeying a flag person’s orders

Failure to obey the orders of a flag person can result in demerit points and a fine of $300 to $600.

In the presence of a traffic control barrier, remotely controlled by a flag person, you must respect the colour of the light. When faced with a red light and a lowered barrier, you must stop your vehicle at least five metres from the barrier, otherwise you could be fined between $300 and $600. When the yellow light is flashing and the barrier is up, you can drive slowly and continue on your way.

Humans at work

A road work site is more than just orange cones. It’s also workers, flag persons, technicians, engineers and others who work around the clock. All these people are not necessarily visible, as they may be hidden behind machines, material or structures. They are not always protected by cement-block barriers. For example, workers who install signs are in an extremely vulnerable position when installing or removing devices. Be cautious and alert when travelling in road work zones – lives are at stake!
