Drivers are facing a new safety campaign as part of a crackdown on a key Highway Code rule. Cambridgeshire County Council has launched a road safety scheme aimed at protecting vulnerable road users, including cyclists, pedestrians, and horse riders.
Focus on Highway Code Rule 163
The initiative specifically reminds motorists about Highway Code Rule 163, which addresses close passing. The rule states: "A close pass happens when a driver overtakes a cyclist without leaving enough space. It is one of the most common causes of fear, near misses, and collisions on our roads."
Providing adequate space is not only considerate but also a legal requirement. Rule 163, introduced in 2022, advises drivers to allow at least 1.5 metres when overtaking a cyclist at speeds up to 30mph, with more space required at higher speeds.
Benefits of Safe Passing
Giving enough space can prevent serious injuries, reduce stress for all road users, encourage more people to walk and cycle safely, and make roads safer for everyone, regardless of journey length. Whether you drive, cycle, or both, understanding Rule 163 is essential for safer journeys.
Guidance for Different Vulnerable Users
For pedestrians walking in the road where there is no pavement, where pavements are obstructed, or in rural areas, drivers should leave at least 2 metres of space at speeds up to 30mph. More space should be given when travelling faster, and drivers should be especially cautious near children, older people, or groups. Drivers should slow down and be prepared to wait if there isn't enough room to pass safely. Pedestrians may move unpredictably to avoid puddles, uneven surfaces, or traffic, so passing slowly and wide helps reduce risk and fear.
When overtaking horses, the Highway Code advises drivers to leave at least 2 metres at speeds up to 30mph, pass wide and slow (ideally at no more than 10mph), and avoid sounding the horn or revving the engine. Drivers should be patient and wait behind the horse if the road is too narrow to overtake safely. Horse riders may signal to drivers to slow down, and following this advice helps protect riders, drivers, and the animal.
Signage Trial Underway
Temporary road signs will be in place from April 2026 through to September 2027 as part of a signage trial. If successful, the signage, a version of which is already in use elsewhere in the UK, may be considered for longer term use in England.
