Motorway Driving: Confident at Higher Speeds

Motorways are statistically the safest roads, but only when drivers plan ahead, use lanes correctly, and stay alert to changing signals.

• National speed limit is 70 mph unless signs show otherwise—always adjust for weather and traffic.
• Use the left lane unless overtaking; keep middle and right lanes for passing only.
• Hard shoulders are for emergencies; on smart motorways, follow the overhead signs for lane status.

• Use the slip road to match motorway speed, checking mirrors and blind spots before merging.
• Signal early when leaving and move into the left lane in good time—do not cross solid lines.
• If you miss your exit, continue to the next junction; never stop or reverse.

Plan overtakes early, checking mirrors and blind spots, signalling, and moving smoothly into the next lane. Pass with a safe gap and return to the left lane as soon as it’s clear. Avoid undertaking unless traffic is moving in queues.

• Obey red ‘X’ lane closures—driving in a closed lane is illegal and dangerous.
• Variable speed limits manage flow; stick to the displayed limit even if lanes look clear.
• Use emergency refuge areas if you break down and contact National Highways via the SOS phone.
