Having the right accessories in your car during a rainy day can help you stay safe and prepared for unexpected situations. Here are some accessories that are helpful to have:

1. Umbrella: Keep a compact or folding umbrella in your car to protect yourself from rain when you step out.

2. Raincoat or Poncho: A raincoat or poncho can be useful if you need to do any work outside the car, such as changing a tire or checking the engine.

3. Towels: Keep a few absorbent towels in the car to dry off wet surfaces or wipe down windows if they fog up.

4. Extra Clothes: It’s always a good idea to have a spare change of clothes, including socks and shoes, in case you get soaked or need to change due to any emergency.

5. Windshield Wipers: Make sure your windshield wipers are in good condition and replace them if needed. Clear visibility is crucial when driving in the rain.

6. Rain-X or Similar Water Repellent: Applying a water repellent treatment like Rain-X to your windshield can improve visibility by causing rainwater to bead up and roll off quickly.

7. Non-Slip Floor Mats: Wet shoes can make your car’s floor slippery. Consider using non-slip floor mats to prevent any accidental foot slippage while driving.

8. Emergency Kit: It’s essential to have a well-stocked emergency kit in your car at all times, regardless of the weather. Include items such as a flashlight, first aid supplies, jumper cables, reflective warning triangles, and a basic toolkit.

9. Portable Phone Charger: In case of an emergency or if you need to make a call, a portable phone charger will ensure that your phone has enough power.

10. Plastic Bags: Keep a few plastic bags or waterproof pouches in your car to protect electronic devices, important documents, or any other valuables from getting wet.

Remember, during heavy rain or severe weather conditions, it’s best to avoid driving if possible. If you must drive, always exercise caution, reduce your speed, and maintain a safe distance from other vehicles.
