Big trucks can't stop, turn or see like cars. Their blind spots are huge, and a crash with one is rarely a fair fight. Stay out of their 'no zones', don't tailgate, and give them room to turn.

Truck no zones, and giving a truck room for a wide right turn

Know the rule

Don't cruise beside a truck's right side. If you end up there, pull ahead or fall back quickly, and grip the wheel firmly—airflow between the vehicles can pull them together.

Handbook p. 52 ↗

Know the rule

Never tailgate a truck. Stay at least 50 feet back if you expect the driver to see you; you're far enough back when you can see the truck's side-view mirrors.

Handbook p. 52 ↗

Know the rule

If you can't see the truck driver in their side-view mirror, the driver can't see you.

Handbook p. 52 ↗

Know the rule

Semi-trailers make wide turns, especially in urban areas. Larger vehicles need more space to turn—give it to them, and watch the lights and markings on large vehicles.

Handbook p. 52 ↗

Put it into practice

A tractor-trailer ahead signals right and swings left to start its turn. Don't squeeze into the gap on its right. Stay back where you can see its mirrors and let it complete the turn.
