Key rules
- § 2.8.2p. 2-19
Objects that look harmless, like boxes or sacks, may hold heavy material that can damage your truck. Watch for debris early so you can steer clear of it without sudden, unsafe moves.
Hazardous Roads
- § 2.8.3p. 2-20
When only the front or rear of a vehicle shows and you can't see the driver, that driver can't see you either. Expect the vehicle to move into your lane and be prepared to stop.
