What are warning signs?

Warning signs are part of the UK road and traffic sign system used to give drivers and riders early notice of hazards, bends, junctions, crossings and other changes in the road ahead. They help you spot danger in good time, adjust your speed and position, and plan your journey safely and confidently.

You'll usually see:

  • Junction and bend warning signs for sharp bends, crossroads, T-junctions and staggered junctions.
  • Road layout and hazard warning signs such as road narrows, hump bridges, level crossings, steep hills and traffic queues.
  • Vulnerable road user warning signs including pedestrians, children, cyclists, horses and animals in the road.

Understanding these warning signs is essential if you regularly drive on unfamiliar roads, in busy towns and cities or on rural routes - and they can all appear in your DVSA driving theory test and hazard perception test.
