The UK parliament begins consideration of the Road Safety Bill today. The sweeping legislation's most significant provision would outlaw the use of radar and laser detectors which warn motorists of upcoming speed traps. GPS locators would not be affected. The legislation would also double the penalty for using a mobile phone while driving to £60 with three points against the driver's license.

Shadow Transport Secretary Tim Yeo will attempt to amend the bill to outlaw speed bumps. "Superficially, road humps may seem an attractive solution. But they probably do more harm than good," Yeo said. "Both safety and environmental considerations are better served by cars traveling at a steady 20mph rather than constantly speeding up and slowing down."

Yeo argues that the roadway obstacles slow down emergency vehicles and increase pollution.

It would also allow courts to force the worst drink-drivers to retake their driving tests.

Other measures include clear guidance on how fast emergency vehicles can travel, more retraining courses for bad drivers and allowing police better use of motor insurance information.
