When you can see well ahead and the road conditions are good, you should:
- drive at a steady cruising speed which you and your vehicle can handle safely and is within the speed limit (see the Speed limits table)
- keep a safe distance from the vehicle in front and increase the gap on wet or icy roads, or in fog (see Rules 126 and 235).
You MUST NOT exceed 70 mph (112 km/h), or the maximum speed limit permitted for your vehicle (see Speed limits table). If a lower speed limit is in force, either permanently or temporarily, at road works for example, you MUST NOT exceed the lower limit. On some motorways, mandatory motorway signals (which display the speed within a red ring) are used to vary the maximum speed limit to improve traffic flow. You MUST NOT exceed this speed limit.

The monotony of driving on a motorway can make you feel sleepy. To minimise the risk, follow the advice in Rule 91.
You MUST NOT reverse, cross the central reservation, or drive against the traffic flow. If you have missed your exit, or have taken the wrong route, carry on to the next exit.
