Speed Limits

Know the limit, stay within it.

Drive within the limit and at a speed and position that gives you and everyone else a comfort zone. Then, if someone makes a silly mistake you’ve got time and space to deal with it ­ no problem, no fuss. Know the limit, stay within it.

Ease off and hang back, that way you’ll have more chance of spotting the unexpected.

What’s the limit?

In a built up area with street lamps the limit is 30mph, unless an alternative speed is displayed, backed up by small reminder signs.

Built up area and street lamps the speed limit is 30mph

There are no reminder signs in areas with a 30mph speed limit or where the national speed limit applies, so if you are in doubt, drive at a speed that keeps you under 30mph.

Missing a speed limit change is no excuse. It’s your responsibility to know the limit and stay within it.

Keep a look out for changes in the speed limit. Here are some typical situations at which a change is likely:

  • A change in the road layout
  • On entering or leaving a built up area
  • Just before or after a junction

Signs and advice

The National Speed Limit
National Speed Limit This sign means the National speed Limit
National Speed Limit Single Carriageway Maximum Speed Limit 60mph mph
National Speed Limit Dual Carriageway Maximum Speed Limit 70mph mph
National Speed Limit Motorway Maximum Speed Limit 70mph mph
These limits apply to car, motocycles and car-derived vans

Try 3rd gear in 30 zones.

Sometimes it can be a struggle to stay under 30mph, particularly in modern quiet vehicles, or if you have a big engine. Try using third gear to control your speed. The natural speed of the car in third should keep you around 30mph or below and will reduce the likelihood of you accidentally slipping over the limit.
