Overtaking trucks
Pass large vehicles safely
Trucks and large vehicles present unique overtaking challenges: large blind spots, significant wind effects, and long passing distances. Understanding these factors ensures safe overtaking.
Why this matters
Truck blind spots can completely hide cars. Wind turbulence from large vehicles affects smaller vehicles. Misjudging overtaking distances on such long vehicles is dangerous.
Key actions to take
- Only overtake where visibility is clear ahead
- Build speed before pulling out
- Expect wind turbulence as you pass
- Allow plenty of space before returning to lane
- See the truck in your mirror before pulling in
- Be extra cautious in crosswinds
Do
- Assume the truck driver cannot see you
- Flash lights before overtaking if appropriate
- Pass trucks promptly: do not linger alongside
- Give extra space in wet weather for spray
Don't
- Overtake on hills or curves
- Cut back in too soon after passing
- Linger in the truck's blind spots
- Attempt to overtake in strong crosswinds
Important warning
Truck blind spots extend well beyond what most drivers realize. If you cannot see the driver's face in their mirror, they cannot see you. Never linger in these zones.
Pro tips
- The longer the vehicle, the more space needed
- Trucks create a vacuum you will feel when passing
- If you cannot see the truck's mirrors, they cannot see you
