California DMV Permit Test (Class C)Traffic Signs and SignalsEasy
You see a white rectangular sign with a black symbol of a truck with a diagonal line through it. What does this sign indicate?
- ATruck weighing station ahead.
- BTrucks must use the right lane.
- CTruck parking area ahead.
- DNo trucks allowed on this road.
Show answer & explanationAnswer & explanation
Correct answer: D. No trucks allowed on this road.
A red circle with a diagonal line (or a diagonal line through a symbol on a white sign) always indicates 'No' or 'Do Not'. Therefore, a truck symbol with a diagonal line means 'No Trucks'.
Why the other options are wrong
- A. This is incorrect; weighing stations have specific signs, not prohibitory symbols.
- B. This is incorrect; lane use signs for trucks are different and don't typically use this prohibitory symbol.
- C. This is incorrect; the diagonal line indicates a prohibition.
Prohibitory Symbol (General)
A red circle with a diagonal line through it, or a diagonal line through a symbol on a white sign, indicating that an action or vehicle type is forbidden.
- Always means 'No' or 'Do Not'.
- Appears on regulatory signs (white background).
- The symbol inside indicates what is prohibited.
Memory trick: A slash means 'stop it, don't do it, not allowed here!'
