Talk to a motor mechanic about how a vehicle’s braking or stopping distance is affected by: (i) wet roads, (ii) worn-out tyres, (iii) higher vehicle mass, (iv) driving at night, (v) fog, (vi) severe weather (rain, snow, storm), and (vii) driver reaction time. Using this information, design safety posters for your school and prepare a short skit to present it in the assembly.

Stopping distance increases on wet roads and with worn tyres (less grip), with a heavier vehicle (more momentum), at night and in fog (less visibility, later reaction), in severe weather, and with a slower driver reaction time (longer reaction distance before braking). Posters should urge lower speeds and larger following gaps in these conditions.
