The monotony of driving on motorways and other high-speed roads can make you feel sleepy. To minimise the risk, follow the advice in Rule 91 about ensuring you are fit to drive and taking breaks.
Service areas are located along motorways to allow you to take breaks and to obtain refreshments. Refreshment and rest facilities on the local road network may also be accessible from motorway exits.
