General rules, techniques and advice for all drivers and riders
This section should be read by all drivers, motorcyclists, cyclists and horse riders. The rules in The Highway Code do not give you the right of way in any circumstance, but they advise you when you should give way to others. Always give way if it can help to avoid an incident.
