In Ukrainian vehicle safety rules, how should tyre pressures be checked to ensure accurate measurements?
Answer and explanation
Correct answer: C. When tyres are cold (before driving or after resting for at least several hours)
- Step 1: Under Ukrainian Traffic Regulations (PDR) and vehicle safety standards, Frictional highway heat expands air inside tyres, giving falsely elevated pressure readings. Answer: When tyres are cold (before driving or after resting for at least several hours). Why not the others: Immediately after high-speed highway cruising on a hot afternoon does not represent the statutory Ukrainian safety requirement.
