Which sign restricts the width of a vehicle?

• A. No Left Turn
• B. Give Priority To Vehicles From Opposite Direction
• C. No Vehicles Over Width Shown
• D. No Buses Over 8 Passenger Seats

Answer: (C)

Signs that limit width tell you the maximum overall width allowed beyond that point. If your vehicle is wider than the number shown, you must not proceed because it could not safely pass through. Width is the total span of the vehicle, including protrusions like wing mirrors.

The sign No Vehicles Over Width Shown communicates this limit directly: the width shown is the maximum allowed, so wider vehicles are prohibited. Other signs deal with turning restrictions or different limits (for example, height or seating), so they don’t address how wide a vehicle can be.
