People who hog the middle lane on motorways or tailgate other drivers could be fined £100 if they are spotted by police.
Until now this type of careless driving has gone unpunished because it is difficult to take the cases to court. The authorities hope that on the spot penalties will be enough to encourage motorists to drive more considerately. Kate Bunkall has been looking at the problem.
The Games Lane on the eastbound M4 into London opens today to help people get to Olympic venues.
The lane is in the previous M4 bus lane which operated for 3.5 miles between junctions 3 and 2 on the Londonbound carriageway.
The M4 is part of the Olympic Route Network and provides an access route for members of the Games Family including athletes, their officials and equipment arriving at Heathrow for their journey to the Olympic Village in Stratford.
80% of Games Family arrivals are expected to pass through this way.
The lane will operate from Monday during the period when most of the Games Family will arrive. The M4 Games Lane will have variable signs which allow the lane to be activated when needed for periods between 5am and 10pm.Outside these operational periods the lane can be used by general traffic.
Motorways in the South are expected to be among the first to trial new 80 mph speed limits. The M20 in Kent from Junctions 4 to 7 and the M25 from Junction 10 to 16 are thought to be the first being considered.
It is because they have variable speed limits so speeds could be raised at quiet times and lowered at congested parts of the day.
It comes following pressure from drivers. The AA has welcomed the move, but safety group BRAKE say the Government is gambling with lives.
