- Geotab Drive App
If unexpected adverse driving conditions slow you down, you may drive up to 2 extra hours to complete what could have been driven in normal conditions.
- This means you could drive for up to 13 hours, which is 2 hours more than allowed under normal conditions.
- Adverse driving conditions mean things that you did not know about when you started your run, like snow, fog, or a shut-down of traffic due to a crash.
- Adverse driving conditions do not include situations that you should have known about, such as congested traffic during typical “rush hour” periods.
- Even though you may drive 2 extra hours under this exception, you must not drive after the 14th consecutive hour after coming on duty, and you must comply with the minimum 30-minute rest break provisions.
