The law allows driving in summer:
- Correct answer: All the answers are incorrect.
- When the lights dont work.
- With no windscreen wipers.
- When the treads of the tires are less than 1 mm deep.
Why this is the answer
The correct answer in the official bank: All the answers are incorrect.
Even in daytime and in summer, a vehicle must be roadworthy at all times. Lights are needed by day too, for signalling, braking and poor visibility, and wipers are needed to clear dust, dirt or sudden rain from the windscreen. Tyres worn below the legal tread depth are dangerous in any season and are prohibited. So none of the options is allowed.
