No deposit car rental in Dubai

Correct. On these 7 cars no amount is blocked or charged on your card as a deposit. You pay the rental cost, insurance is already included, and that is the end of it.

Insurance is included, but you remain liable up to that provider's insurance excess — a figure the provider confirms with you before you book. Damage below that figure is on you; above it, the insurer pays. Ask for the exact excess before you book; the provider states it in writing.

Yes. A credit card in the driver's name is still required for identification and for costs billed after the rental, such as Salik tolls and traffic fines, even when no deposit is blocked.

Typically up to 30 days, because Salik tolls and traffic fines take weeks to post against the vehicle. On these cars nothing is held at all — tolls and fines are simply billed to your card afterwards instead.
