Before setting out during the rainy season, ensure your vehicle is in optimal condition. Check the tyres for adequate tread depth to prevent skidding on wet roads. Ensure the wipers are functional and the windshield washer fluid is topped up for clear visibility. Test the brakes and lights, as they are crucial for safety in low-visibility conditions. Carry an emergency kit with essentials like a flashlight, first-aid supplies, and basic tools in case of breakdowns.
