The Highway Code is essential reading for everyone who uses the road (and this applies to pedestrians and cyclists as much as to learners and fully qualified drivers). Many of the rules are legal requirements (rules that state you ‘MUST/MUST NOT’ do something). Disobeying these rules is a criminal offence and can result in a fine, penalty points on your licence or disqualification from driving (and, in the most serious cases, a prison sentence). Failing to comply with other rules (rules using the advisory wording of ‘should/should not’ or ‘do/do not’) will not lead to prosecution but could be used in evidence in court cases to determine liability.
I have started to post a weekly reminder of some of the more important or lesser known rules on my Facebook Business Page, so if you visit my page and like it, it will help you build or refresh your knowledge (and may be helpful as part of your preparation for the Theory Test).
