It would appear that I am not alone in my anxiety and apprehension when joining and being joined by sliproad traffic on UK motorways. The Highway Code manual is by no means specific or clear cut in this regard. Rule 233 states "you should give priority to traffic already on the motorway". The word “should” appears weak when compared to “must’ and “must not” which are used liberally in the manual. “Should” implies that you are not obliged or required to conform to the regulation, thus leading to uncertainty and indecision and therefore potential for an accident. Rule 143, which in motorway terms is related to Rule 233, is much more precise and clear when it states " do not force another vehicle to swerve or slow down ". Leaving the Highway Code manual aside, if the two chevron concept was adopted in these motorway areas to accommodate joining traffic, would it both minimise and facilitate the need for the more hazardous manoeuvres of lane switching and slowing down and lead to less stress and safer motoring for all.
