Who has priority at a motorway junction involving an entry slip road? I had long believed that the pecked or dashed line where an entry slip comes onto the nearside lane of a dual carriageway or motorway had the same effect as a ‘Give Way’ sign indicating that it is the responsibility of drivers joining the major road to give way to those already on that highway. Increasingly, I see vehicles move out slip roads onto the inside lanes without apparent regard for the approach, often at high speed, of cars already in that lane. They give no thought to the fact that the vehicle in front of which they are pulling (1) is lawfully travelling at a much higher speed that they are themselves; (2) may be closely followed by another vehicle doing a similar speed and thus rendering braking by the front vehicle potentially dangerous; and (3) may have another vehicle on their offside so removing the option of moving into an outer lane. Although I have yet to witness an actual impact in these circumstances, I have seen many near misses, all caused by drivers who believe that they have priority when joining a major road. What is the law here? What does the Highway Code say about this point? Your column could be a useful tool to educate the motoring public on this matter.
