Which sign restricts the length of a vehicle or its combination?

• A. No Vehicles Over Height Shown
• B. No Overtaking
• C. No Vehicle Or Combination Of Vehicles Over Length Shown
• D. No Tow Caravans

Answer: (C)

The sign that restricts length shows the maximum overall length allowed for your vehicle, including any trailer, caravan, or load it’s towing. When you see it, you must not proceed if your vehicle’s total length exceeds the number shown on the sign. This helps protect narrow roads, bridges, or tunnels where a longer vehicle wouldn’t fit safely.

Other signs are about different limits: a height limit sign controls how tall you can be, not how long; a no overtaking sign forbids passing other vehicles; a no tow caravans sign prevents towing a caravan at all.
