Keep your distance from the car in front, even if the driver appears to be driving safely. This behaviour is not as safe as you think: the distance available to you in the event of braking or slowdown may be insufficient for the speed you are both driving at.
Avoid overtaking where possible and if you are forced to overtake, indicate immediately and then return to your original lane.
Don't be distracted by what is happening on the opposite lane: you may have insufficient time to see what is happening right in front you.
Do not drive on top of lane edge lines.
Avoid stopping on the hard shoulder; if forced to stop, switch on the hazard lights and side lights. Motorists should stay in the specially equipped area or in lay-bys in order to avoid the danger of being hit by vehicles in transit.
