Particularly vulnerable pedestrians. These include

• children and older pedestrians who may not be able to judge your speed and could step into the road in front of you. At 40 mph (64 km/h) your vehicle will probably kill any pedestrians it hits. At 20 mph (32 km/h) there is only a 1 in 20 chance of the pedestrian being killed. So kill your speed
• older pedestrians who may need more time to cross the road. Be patient and allow them to cross in their own time. Do not hurry them by revving your engine or edging forward
• people with disabilities. People with hearing impairments may not be aware of your vehicle approaching. Those with walking difficulties require more time
• blind or partially sighted people, who may be carrying a white cane or using a guide dog. They may not be able to see you approaching
• deafblind people who may be carrying a white cane with a red band or using a dog with a red and white harness. They may not see or hear instructions or signals.
