A public consultation is running until August 2026 on proposals to introduce 20mph speed limits on several roads in Cambridge, sparking debate over road safety and enforcement
Cambridgeshire Live readers remain divided over proposals for more 20mph speed limits in Cambridge, with firmly held opinions on road safety, enforcement, and the available evidence. Some are calling for a consistent city-wide policy, while others argue the restrictions will do little to change driver behaviour or reduce accident rates without more robust measures.
According to Cambridgeshire County Council, more than 100 people have been seriously injured across these routes since 2017. A public consultation is running from July 1 to August 5, 2026. The proposed 20mph speed limits include: Chesterton Lane, Chesterton Road (Mitcham’s Corner to Magdalene Bridge), Corona Road, Milton Road (Mitcham’s Corner junction only), and Northampton Street.
A number of additional roads are also included. The council said the routes put forward for reduced speed limits are those which attracted the greatest public support, as well as several known crash hotspots.
Regarding Cottenham, one reader was forthright. Tartan53 says: “Not all villages want 20 mph, in Cottenham a vote taken more people were against a 20mph limit over ruled by county council imposed and it has not made any difference, traffic still ignoring it, speed bumps are required… Total waste of money.”
Freddly adds: “This person hasn’t observed how traffic works in Cambridge. If 20% of drivers comply at busy times (and increasingly, since the food delivery ‘boom’, that means all day), then that holds up the 80% who would like to go faster. The ‘dangerous overtaking’ thing is a figment; there is too much opposing traffic. We need to follow other cities where the default is 20 on restricted roads (that is, streets with street-lights).”
Lovelycardriver writes: “Alex Beckett’s claim of ‘over 100 injuries since 2017’ doesn’t match any published council data. When asked to show where that figure comes from, he doesn’t engage. It feels less like evidence‑based policy and more like another push to restrict motorists and reshape Cambridge without transparent facts. People deserve clear data, not headline numbers that can’t be verified.”
Johnsm feels: “The door to door average speed through the city is generally below 20MPH. (Take any realistic journey in Google Maps to and from within Cambridge, even at night time, even on 30mph roads). That average speed is generally dominated by traffic lights. A 20mph speed limit isn’t going to affect the timeliness of the majority of journeys more than a minute or two. It’ll just stop drivers from needlessly accelerating to 30 only to brake 5 seconds later. It’ll save the driver on fuel/brake pads, and the general taxpayer in road wear and tear.”
Brexit498 comments: “Cherry Hinton Rd was made a 20 MPH limit 15 years ago, it made no difference to the accident rate. As others have said, where is the evidence/statistics for the injury claim broken down by time, day, season, speed, alcohol/drug use, etc? As with Adams Rd, the figures don’t support the policy decision.”
Aljan says: “The anti-motorist faction strikes again. Perhaps the councillor could publish his statistics with a breakdown of how it happened, who was at fault, etc. Someone slipping on an icy pavement and breaks a limb, serious injury but no vehicle involved for example. His lack of statistics would indicate he is on shaky ground with his claims.”
Carbonneutralfeminist writes: “What is desperately needed is many more speed cameras on 20mph zones. Drivers regularly drive between 30 and 50mph in them, breaking the highway code like they haven’t read it. You can’t complain about imaginary cyclists going through reds when you do that!”
Over on our Facebook page, Clive P asks: “Why only 20mph? Wouldn’t 15 mph be better, or maybe even 4 mph? You could then have a man with a flag walk in front of each vehicle.”
Gareth S P comments: “Just further pushing the onus onto motorists to think for and compensate for the lack of common sense and awareness of other road users.”
Colin D thinks: “Make it simple. Once you’re off the A14, the motorway or any other route into Cambridge, it’s 20mph. Such zones are cleaner, safer, quieter and reduce congestion. None of this rubbish with variable limits, just make the whole zone 20mph once you’re off the main roads and into Cambridge.”
Do you think that 20 is indeed plenty? Comment below or HERE to have your say.
