More 20mph roads, more cameras, more penalties: Why London taxi drivers must stay alert

London taxi drivers are being urged to pay closer attention to changing speed limits as camera enforcement continues to expand across the capital, according to advice from Licensed Taxi Drivers’ Association (LTDA) Airport Representative Suzanne Sullivan.
Writing in the LTDA’s Taxi newspaper, Sullivan highlighted the growing challenge facing professional drivers as more roads transition from 30mph and 40mph limits to 20mph restrictions. The shift, driven by Transport for London and local borough road safety policies, is creating what she described as an increasingly difficult environment for drivers trying to stay compliant.
Sullivan warned that for licensed taxi drivers, a speeding offence carries consequences that go beyond a financial penalty. She said: “A speeding fine is not just an inconvenience. For licensed taxi drivers, it can mean penalty points, increased insurance costs, attending a speed awareness course and, in serious cases, questions over fitness to hold a licence.”
The warning comes as speed camera enforcement reaches record levels nationally. Sullivan cited figures showing police issued almost 489,000 speeding tickets on 20mph roads during 2024, representing a significant increase on the previous year. London remains one of the most heavily enforced regions, with a growing proportion of offences recorded on lower-speed roads.
A key concern raised by Sullivan is the frequency with which speed limits can change over relatively short distances. She pointed to routes where motorists move from a 40mph road into a 30mph zone, only to encounter a speed camera shortly afterwards. In some cases, cameras are positioned close to changes in speed limits, increasing the likelihood of drivers being caught if they fail to adjust their speed quickly enough.
“Enforcement is widespread, cameras are active, and drivers who fail to notice a change in limit are increasingly likely to receive a Notice of Intended Prosecution (NIP) through the post,” Sullivan wrote.
The issue is particularly relevant to taxi drivers who spend long hours behind the wheel and often work across multiple boroughs, each with differing traffic management policies. More than half of London’s roads are now subject to a 20mph limit, while 21 of London’s 33 boroughs have adopted widespread default 20mph restrictions across much of their local road networks.
Sullivan believes awareness remains the most effective defence. She advised drivers not to rely on memory when travelling familiar routes, noting that speed limits can change over time and that enforcement activity may increase without drivers immediately noticing.
“Never rely on memory when driving a familiar route,” she said. “Pay close attention to speed limit signs, particularly where limits change, and read signs where they are provided.”
She also urged drivers to remain especially vigilant when moving from major roads onto borough-controlled streets, where speed limits can quickly fall from 30mph to 20mph.
For professional taxi drivers, the consequences of repeated speeding offences can become far more serious than a single fine. Accumulating penalty points may trigger licensing concerns, while higher insurance premiums can increase operating costs at a time when many drivers are already facing significant business pressures.
Sullivan concluded that maintaining the high professional standards associated with London’s taxi trade now requires constant awareness of changing road regulations. “In today’s road environment, that knowledge must include constant awareness of changing speed limits,” she said. “A moment’s lapse can result in a fine, points on your licence and unnecessary stress.”
