Lord Berkeleyasked Her Majesty's Government:
What research evidence informed their decision to require speed cameras to be painted yellow. [HL5826]
§ Lord Macdonald of TradestonNone. This requirement has been in place only since 1 June but feedback already suggests that there is even better compliance with the speed limits at sites that operate yellow cameras.
Lord Berkeleyasked Her Majesty's Government:
What proportion of the following vehicles are recorded as exceeding speed limits (a) cars where the speed limit is 30 miles per hour; (b) cars where the speed limit is 70 miles per hour; (c) lorries where the speed limit are 30 miles per hour; (d) trains at any speed. [HL5827]
§ Lord Macdonald of TradestonThe estimates for cars and lorries exceeding the speed limit on roads with a 30 mph is given in the following table.
Percentage of cars and lorries recorded exceeding the speed limit on roads with a 30 mph speed limit: 2001 Exceeding 30 mph limit More than 5 mph over limit Cars 65 32 Rigid 2 axle HGV 55 20 Rigid 3 axle HGV 51 15 Articulated 3 axle HGV 44 12 Rigid/articulated 4 axle HGV 49 16 Rigid/articulated 5 or more axles HGV 42 10 In 2001 on motorways 54 per cent of cars were recorded as exceeding the speed limit. On dual carriageway roads, with a 70 mph speed limit for cars, 51 per cent of cars were recorded exceeding the speed limit.
The department does not hold figures on trains exceeding speed limits. However, Railtrack Plc has advised that for the period 31 March to 20 July 2002 there were 53 incidents of trains overspeeding on the national rail network. This equates to 0.01 per cent of trains exceeding speed limits.
