Reading the fine print without slowing down the pickup.
The agreement covers far more than the price — mileage limits, fuel policy, permitted drivers, and insurance terms are all spelled out, and it's worth a quick read before signing rather than after a problem arises. Asking the counter staff to clarify anything unclear takes a minute and can save a costly misunderstanding later.
Keep a copy of the signed agreement, whether digital or printed, accessible throughout your trip in case a question comes up on the road.
