The adverse driving exemption allows you to extend both your driving time by 2 hours and your on-duty time by 2 hours. You can extend your hours under the following conditions:
- When using the federal US rule set
- When facing extreme weather conditions; for example, ice, sleet, or high wind
- When facing adverse road or traffic conditions that you or your carrier were unaware of when starting a shift
- Once per shift, as many times per cycle as required
- When not currently within a rest break of more than 10 hours, which is used to reset your daily hours
The adverse driving exemption is off by default and normal HOS rules are used. To enable the adverse driving exemption on a day when you are experiencing adverse driving conditions:
- Go to the HOS Status screen.
- Tap Actions in the lower part of the screen.
- Tap Exemptions.
- Tap the toggle next to Adverse Driving Exemption so that the indicator turns blue.
- If you are certain that you want to enable the exemption, tap Done. Once you have tapped Done, you cannot disable the exemption. The Adverse Driving Conditions text is shown in gray next time you open the Exemptions screen.
- In the dialog box that opens, enter a mandatory description of the driving conditions that you are currently experiencing. The description can be up to 55 characters in length.
- Tap OK.
If you are eligible for the adverse driving exemption, you can also enable the exemption from the Exemptions screen that appears when you sign in to WorkPlan.
When you have enabled the adverse driving exemption, you cannot manually disable the exemption. The exemption is automatically disabled after a 10-hour reset.
When the adverse driving exemption is enabled, the period of time when you are using the exemption is shown on the HOS chart with the label AdC and on your Driver's Daily Log with the label ADVERSE COND ON:
