The Rise of 20mph Speed Limits in Urban Areas
If you’re a driver in the UK, you may have noticed more and more 20mph signs appearing on roads where you once drove at 30mph. This new 20mph speed limit is quickly becoming the new standard for urban and residential roads as part of a nationwide move aimed at creating safer communities for everyone while also encouraging people to walk and cycle more.
However, this shift can bring new questions and concerns for drivers. How does this affect your daily commute? What are the legal consequences if you’re caught exceeding this new limit? Although it may seem like a minor offence to exceed this 20mph speed limit, the penalties can be significant. Our motoring experts at DPP Law will walk you through why these limits are being put in place, what happens if you fail to comply and how we can help if you have been charged with a speeding offence.
Why Are 20mph Speed Limits Becoming More Common?
The simple answer is safety. Lower speeds give drivers more time to react and stop, preventing countless collisions from ever happening.
In London, the introduction of 20mph limits led to:
- A 34% reduction in people killed or seriously injured
- A staggering 75% drop in child fatalities
- A 25% fall in overall collisions in the city centre
These limits are meant to encourage more walking and cycling by making streets feel safer for everyone, especially vulnerable road users. The goal is to create quieter, more pleasant neighbourhoods where communities can thrive.
How Are 20mph Speed Limits Enforced?
If you’re caught speeding in a 20mph zone, the process is the same as any other speeding offence. Enforcement happens through speed cameras, mobile police checks and community speed watch initiatives.
If you are caught speeding, the process typically starts with a Notice of Intended Prosecution (NIP) being sent to the vehicle’s registered owner. From there, you can usually expect one of three outcomes:
- A Speed Awareness Course: For minor offences (typically between 24-31mph in a 20mph zone) and if you haven’t attended a course in the last 3 years, you may be offered this option. While you have to pay for the course, you avoid getting penalty points on your licence.
- A Fixed Penalty Notice (FNP): You’ll receive a £100 fine and 3 penalty points on your licence; This is the most common outcome.
- A Court Summons: For more serious speeding offences, or if you already have a high number of points, your case will be referred to court. Here, the speeding penalties can be much higher, with fines based on your weekly income and the risk of a driving ban.
Can You Lose Your Licence For a 20mph Offence?
Under certain circumstances, you may lose your licence for a 20mph speeding offence. This usually happens in two ways:
- Immediate Disqualification: If you are caught driving at a significantly high speed (for example, 45mph or more in a 20mph zone), the court has the power to ban you from driving on the spot. A ban of up to 56 days is a likely outcome for these scenarios.
- ‘Totting Up’ Ban: This is the most common reason for disqualification; If you accumulate 12 or more penalty points on your licence within a 3-year period, you will face a mandatory driving ban of at least 6 months. For a driver who already has 9 points, a single 3-point ticket for doing 25mph in a 20mph zone is enough to trigger this ban.
For new drivers, the rules are even tougher; if you get 6 or more points within the first two years of passing your test, your licence will be revoked completely and you will have to retake both your theory and practical tests.
Why Early Legal Advice Matters?
Facing a speeding allegation can be incredibly stressful and often people don’t realise they may have a defence, so they simply accept the penalty. This is where seeking advice from specialist motoring law solicitors can make all the difference.
The motoring law experts at DPP Law understand that your driving licence is often essential for your job, your family, and your independence. We are here to offer clear, supportive and professional guidance. An expert driving offences solicitor can:
- Scrutinise the evidence, checking for any procedural errors, such as a late NIP or incorrectly calibrated speed detection equipment, which could lead to the case being dropped
- Check for correct signage as the law requires speed limits to be clearly and properly signposted and if they weren’t you may have a defence
- Build an ‘Exceptional Hardship’ argument if you are facing a ‘totting up’ ban, this involves arguing in court that a disqualification would cause exceptional hardship not just for you but for those dependant on you such as your family or someone you care for
