It’s no fun being sick OTR. In really bad Cades the company may have another driver come get your load and deliver it. If you go to hospital the company may tow your truck to a facility of their choosing while you get bettet. If you are going to be down a long time they may have someone box up your stuff, ship it to your terminal and issue your truck to another driver. If you have bereavement situation they may have you swap loads and let you drive home or park truck & fly home. Company policy varies & situations vary wildly. Work for a company that wants to keep you, not a mega-company. IMO.
