It is important when you pick up your rental car that you check for damage. You will be provided with a vehicle condition report. If you find any damage not listed on the report, you will need to inform the car rental representative so it can be added. Many customers also take photos of the vehicle in its current condition before they leave the depot. If the vehicle is damaged or stolen while it is in your possession, you are responsible regardless of whether you were at fault.
If you take the vehicle to any prohibited areas, or use the vehicle in a way that does not adhere to the terms and conditions of your rental agreement, it will void any insurance products you have purchased. Therefore, you will be liable to pay the full excess amount.

When you return the vehicle, the car rental company representative will check the vehicle for any new damage. If anything extra is found, you will be provided with a copy of the Vehicle Condition Report notating the damage that has been found. You will have to pay any estimated damage charges. If the actual cost of the damage repairs turns out to be less than what you were charged, you will be refunded the difference. If the damage is significant it may need to be assessed by a third party.
If you are not present for the inspection, you will receive notification from the car rental company informing you of the damage that was found, with images. Your credit card will be charged for the cost of repairs.
