A report commissioned by the previous Labour government is expected to call for the legal alcohol limit for drivers to be lowered.
Sir Peter North's study is set to recommend that the existing limit of 80mg of alcohol per 100ml of blood is cut to 50mg, which would reflect the level across most of Europe. The new Conservative-Liberal Democrat administration, however, is thought to be wary of making a change. If more people are given points or bans for drink driving they are likely to have to pay higher car insurance premiums.
Other recommendations in Sir Peter's findings are believed to be random breath testing, the removal of second breathalyser tests at a police station, a 20mg limit for novice drivers and a new offence of driving with an illegal substance in the bloodstream at levels deemed impairing.
There is already an offence which makes it illegal to drive while impaired by a drug but a new offence might make it illegal to drive with named drugs in the system at specified levels.
New Transport Secretary Philip Hammond took receipt of the report last month and it is set to be made public.
