Road Warning Signs and Meanings

Warning signs often take the shape of an equilateral triangle and are used to warn a driver of an impending hazard that might otherwise not be obvious whilst driving.

Both the colour and thickness of the border vary from country to country. A large part of the theory test is designated to road signs.

Warning signs are used to to bring your attention to any hazards, or a particular traffic condition or obstacle that may be up ahead.

This section is detailing the warning signs used on UK roads complete with pictures and meanings. It is important to understand road signs for safety reasons and to aid in passing the driving theory test and practical driving test.
