Overtaking
Overtake only on the right, unless traffic is travelling in slow moving queues and the traffic queue on your right is travelling more slowly than you are. If you intend to move from a slower lane to a faster lane, adjust your speed first.
Before you start to overtake, remember ‘mirror, signal, mirror, manoeuvre’, and look in your blind spots. Check that the way is clear (behind and ahead) and signal well in advance.
Remember that traffic will be travelling a lot faster than on ordinary roads. Be particularly careful at dusk, during darkness, and in poor weather conditions when it is more difficult to judge speed, distance and stopping distance. Signal and return to your original lane as soon as possible.
Gantries
Gantries are structures used to display traffic signs above traffic lanes on motorways and dual-carriageways. They are common and display important information, so make sure you pay attention to them as well as to other signs along the side of the road.
Variable message signs
Variable message signs such as the one displayed below are used on motorways to provide messages and information to motorists and to warn of incidents that may affect traffic conditions and journey times.
Motorists should pay attention to these signs at all times.
