Change Highway Code rules 163 and 212

Rule 163
Overtake only when it is safe and legal to do so.

You should
* not get too close to the vehicle you intend to overtake
* use your mirrors, signal when it is safe to do so, take a quick sideways glance if necessary into the blind spot area and then start to move out
* not assume that you can simply follow a vehicle ahead which is overtaking; there may only be enough room for one vehicle
* move quickly past the vehicle you are overtaking, once you have started to overtake. Allow plenty of room. Move back to the left as soon as you can but do not cut in
* take extra care at night and in poor visibility when it is harder to judge speed and distance
* give way to oncoming vehicles before passing parked vehicles or other obstructions on your side of the road
* only overtake on the left if the vehicle in front is signalling to turn right, and there is room to do so
* stay in your lane if traffic is moving slowly in queues. If the queue on your right is moving more slowly than you are, you may pass on the left. Cyclists may pass slower moving or stationary traffic on their right or left and should proceed with caution as the driver may not be able to see you. Be careful about doing so, particularly on the approach to junctions, and especially when deciding whether it is safe to pass lorries or other large vehicles.
* give motorcyclists, cyclists and horse riders and horse drawn vehicles at least as much room as you would when overtaking a car (see Rules 211 to 215). As a guide:
  * leave at least 1.5 metres when overtaking cyclists at speeds of up to 30mph, and give them more space when overtaking at higher speeds
  * pass horse riders and horse-drawn vehicles at speeds under 10 mph and allow at least 2 metres of space
  * allow at least 2 metres of space and keep to a low speed when passing a pedestrian who is walking in the road (for example, where there is no pavement)
  * take extra care and give more space when overtaking motorcyclists, cyclists, horse riders, horse drawn vehicles and pedestrians in bad weather (including high winds) and at night
  * you should wait behind the motorcyclist, cyclist, horse rider, horse drawn vehicle or pedestrian and not overtake if it is unsafe or not possible to meet these clearances.
Remember: Mirrors – Signal – Manoeuvre

Rule 212
Give motorcyclists, cyclists, horse riders, horse drawn vehicles and pedestrians walking in the road (for example, where there is no pavement), at least as much room as you would when overtaking a car (see Rules 162 to 167). Drivers should take extra care and give more space when overtaking motorcyclists, cyclists, horse riders, horse drawn vehicles and pedestrians in bad weather (including high winds) and at night. If the rider looks over their shoulder it could mean that they intend to pull out, turn right or change direction. Give them time and space to do so.
