Jay is planning a delivery schedule expected to involve 4 hours 20 minutes of driving before reaching a service area. What should he allow for before adding another 40-minute leg?

1. A qualifying break before exceeding 4.5 hours of driving
2. No break because loading time resets driving time
3. Only a 5-minute stop if he stays in the cab
4. A daily rest period after every 4 hours of driving
