In answer to a question on our free California test:
Our tests contains several questions about sharing the road with large trucks.
Two key factors to remember is that trucks have larger blind spots than a normal car and that they make wide turns.
The reason they make wider turns is that the rear wheels travel a shorter distance than the front wheels. See the image above.
To compensate the shorter path of the rear wheels, a driver might need to turn slightly to the left, before turning right.
Never try to get between the truck and the curb when the truck driver is turning. The driver will not be able to see a car that is directly behind them or beside them in their blind spots, so be cautious.
