Major changes to the Highway Code come into effect on Saturday.
Here the PA news agency looks at 10 key rules that are new or clarified:
1. Hierarchy of road users
A new hierarchy means people in charge of vehicles that can cause the most harm in the event of a collision have the greatest responsibility to look out for other road users.
2. Walking, cycling or riding in shared spaces
Cyclists should not overtake people walking or riding a horse in shared spaces closely or at high speed, while pedestrians should take care not to obstruct paths.
3. Positioning of cyclists
Cyclists should make themselves as visible as possible by riding in the centre of lanes on quiet roads, in slower-moving traffic and at the approach to junctions.
4. Pedestrians crossing at junctions
Turning traffic should give way when people are crossing or waiting to cross at junctions.
Traffic must give way to people on zebra crossings.
5. Overtaking cyclists
Drivers travelling at speeds of up to 30mph should leave at least 1.5 metres when overtaking cyclists.
They should give more space when overtaking at higher speeds.
6. Opening car doors
Car occupants should open doors using their hand on the opposite side to the door, making them turn their head to look over their shoulder.
This technique, known as the Dutch Reach, reduces the chances of doors being opened into the path of cyclists and motorcyclists.
7. Overtaking cyclists at junctions
When cyclists are going straight ahead at a junction, they have priority over traffic waiting to turn into or out of a side road, unless road signs or markings indicate otherwise.
8. Cycling in groups
People cycling can ride two abreast but should be considerate of the needs of other road users when in groups.
Drivers should take extra care when entering roundabouts to make sure they do not cut across cyclists.
10. Electric vehicle charging
Electric car owners using a public chargepoint should park near the device and avoid creating a trip hazard from trailing cables.
