Which statement about trucks is true?

• A. Large trucks have shorter stopping distances than passenger vehicles.
• B. Trucks can stop instantly when lights change.
• C. If you can't see the truck driver in his side mirror, he can't see you.
• D. The size of a truck does not affect its visibility to you.

Answer: (C)

The main idea here is how truck visibility and blind spots affect safety. Large trucks have big blind spots along their sides and behind them, so the driver can’t see you if you’re in those areas. If you can’t see the truck driver’s face in his side mirror, chances are he can’t see you either, which is why staying out of those zones is important. This makes the statement the best guidance: you should assume you’re not seen unless you’re clearly visible to the driver in the mirrors.

Trucks also don’t stop instantly; their stopping distances are much longer due to their weight and momentum, so you shouldn’t expect abrupt stops from them. And bigger vehicles do affect visibility and safety: their larger blind spots mean you’re more likely to be missed by the driver if you’re riding alongside or close to them.
