As of 2026, Hertz typically offers a standard 29-minute grace period for vehicle returns. This means that if you return your car up to 29 minutes after the scheduled return time listed on your rental agreement, you will generally not be charged an additional hourly or daily fee. However, once you reach the 30-minute mark, the grace period expires, and you will typically be charged for a full extra hour. If the return is delayed by more than 90 to 120 minutes (depending on the specific location and rate type), Hertz will usually charge you for an entire additional day of rental. It is important to note that the grace period applies only to the "time and mileage" portion of the bill; it does not necessarily apply to daily fees for items like car seats, GPS units, or insurance coverage, which might be billed at a daily rate regardless of the 29-minute window. To avoid these fees, it is always recommended to use the Hertz mobile app to extend your rental in advance if you anticipate being late, as "unauthorized" late returns can sometimes trigger higher "walk-up" rates.
