Common Highway Code mistake made by drivers over 50

The Highway Code is a set of rules that aims to keep all road users safe. The Code has been updated a number of times in recent years, however experts have found that an alarming number of older people remain in the dark about these changes.
Age Co data worryingly reveals that some one in five drivers over 50 have not familiarised themselves with the Highway Code since passing their tests, posing potential risks for everyone on the road. Among the most common rules causing confusion is the fairly new "Dutch Reach" technique.
This safety manouevre involves using the hand furthest from the door to swing it open, thereby twisting drivers or passengers towards the rear and allowing a clear view for any incoming traffic. This is said to be crucial for spotting and protecting any passing cyclists.
However Age Co's insights suggest "almost half of the respondents said that they weren't sure about this one".
While it isn't exactly synonymous with law, much of the Highway Code carries legislative weight, according to the RAC, with binding directives flagged within its pages by imperatives such as 'MUST', 'MUST NOT', unlike the more advisory 'should' or 'should not'.
Official Gov.uk guidance states: "The Highway Code is essential reading for all road users, including pedestrians, mobility scooter users, cyclists, horse riders, drivers and motorcyclists."
An Age Co expert said: "Understanding road safety rules and regulations help keep our roads safe, so it's important to refresh your knowledge regularly to stay up to date with the latest changes."
