1. TYRES - Tyres that are worn, or have low pressures, have less ability to disperse water while you drive. They would also have less friction with the road, which could make the road seem extra slippery when wet.
2. WIPERS - If your wipers are squeaky, shuddering or smearing moisture, you will have poor visibility in wet weather.
3. BRAKES - Rain causes oil and grease to rise to the surface of the road, which makes the road extra slippery. When braking, it is important to come to a slow halt, and keep distance from other cars.
