In reply to Mr Hook (Letters, March 3) - as a matter of law, the bus lane is a separate road. The solid white line between the bus lane and the "normal"

highway means that traffic from one cannot cross into the other. It has the same effect as a solid (single or double) white line on a two-way road.

This means the two roads are separate and traffic can travel at different speeds in either lane. It is not the same as queuing two-lane traffic, where the left lane is permitted to move faster than the right lane.

As a matter of design, bus lanes are intended to allow buses and taxis to move faster along a road than other traffic. Of course, if an accident were to be caused by a speeding bus or taxi, the driver might be liable to prosecution if the speed contributed to the accident.

At a left or right turn across a bus lane, the normal rules apply, just as if the crossing were a junction. The traffic with priority (which is the bus lane traffic) should be careful at the crossover, but the traffic without priority should be even more careful to ensure that the bus or taxi on the "other road" is not travelling too fast, before crossing the bus lane.

The Highway Code covers this - paragraphs 12 and 159.
