DfT publishes vehicle speeds in GB

The Department for Transport has published National Statistics of vehicle speeds in Great Britain for 2004.

The statistics relate to the speeds at which drivers choose to drive in free-flow conditions generally across the road network. The latest figures show that driving in excess of the speed limit remains at a high level on all types of road.

On roads with a 30mph speed limit 53% of cars exceeded the limit compared with 58% in 2003; 25% travelled faster than 35mph, the same as in 2003. Where as 24% of motorcycles were travelling at more than 35mph compared with 29% in 2003.

More than half the cars on motorways and 48% of cars on dual carriageways travelled faster than the speed limit; 19% were travelling faster than 80mph on motorways, and 14% on dual carriageways. The proportion of motorcycles travelling at more than 80mph on motorways remained at 28% in 2004; whilst on dual carriageways the proportion fell from 23% to 21%.

Vehicle Speeds in Great Britain: 2004 uses data collected at 36 sites where a 30 or 40 mph limit applies and at 62 other sites. The sites have been selected so that speeds are not seriously constrained by road layout, traffic congestion or by the proximity of speed cameras.

The speeds are recorded as vehicles pass over an automatic counter and do not represent speeds over a longer distance. They do however provide an indication of compliance with speed limits.
