A driving instructor has warned motorists that accelerating before passing a National Speed Limit sign could result in a fine of up to £1,000, penalty points, or even a driving ban. The rule, which many drivers may have forgotten, states that the new speed limit takes effect only after the sign has been passed, not when it is first seen.
The Common Mistake
In a TikTok video, the instructor @auh.driving, who specializes in automatic driving lessons and mock tests, reminded drivers: "National speed limit starts AFTER the sign, not when you see it." He emphasized that before passing the sign, drivers are still subject to the previous limit, such as 30 mph in built-up areas.
Once a driver passes a National Speed Limit sign on a motorway or dual carriageway, they may legally accelerate to 70 mph, provided it is safe. However, accelerating before reaching the sign is prohibited and can lead to severe penalties.
Penalties for Excessive Speeding
According to the UK Government, being caught speeding 40 mph over the limit is classified as a high-severity offence. Offenders skip a standard Fixed Penalty Notice (FPN) and are summoned to court, where they face a driving ban of 7 to 56 days and a means-tested fine up to £1,000 (£2,500 on motorways).
The RAC notes that magistrates can impose an immediate driving disqualification for extreme speeding. If a ban is avoided, drivers receive four to six penalty points on their licence. Fines are calculated as a percentage of weekly income, typically 75 to 175 per cent, depending on the road and speed recorded.
Key Takeaway
Drivers are advised to wait until they are level with a National Speed Limit sign before accelerating. The new limit begins at the sign's location, not before. Ignoring this rule can result in significant financial and legal consequences.
