30. Curve

A curve is a section of road that changes direction to the left or right. A sharp, unexpected or poorly visible curve can reduce a driver’s view of approaching traffic, stopped vehicles, pedestrians and other hazards.

Drivers should reduce speed before entering the curve, remain within their lane and use smooth steering, braking and acceleration. Warning signs may indicate the direction of the first curve or a series of successive curves.

What makes a bend dangerous in the United Kingdom?

Curves shorten your view of the road ahead and can reduce the margin for correcting a mistake. Drivers may encounter narrow country-road bends with hedges, limited sightlines and sometimes livestock; the safe speed can be well below the posted maximum. The Highway Code specifically advises reducing speed before country-road bends and remaining able to stop within the visible clear distance.

How should you approach a sharp curve in the United Kingdom?

Slow down before the bend, select the correct lane position, look through the curve and steer smoothly. Keep enough grip and visible stopping distance for the road and weather conditions.

Is overtaking safe on a blind bend in the United Kingdom?

No. Do not start overtaking where your view of oncoming traffic is obstructed or where signs or road markings prohibit it. Wait until there is a lawful, clear and sufficiently long view ahead.
