What is rap charge on rental car?

Enterprise offers Roadside Assistance Protection (RAP).

RAP allows Enterprise customers to waive financial responsibility for Chargeable Roadside Incidents such as lost keys, lockouts and fuel outages.

= $3.99/day Canadian Dollars & US Dollars

RAP can be added to online bookings at the branch.

RAP can be added to a rental ticket at any time

NOTE: If you do not expressly waive it, many rental car folks may just add it. Just another way to rip off the public.
