You may stop on a clearway only in emergencies such as a vehicle breakdown, a medical emergency, or after a collision if it is unsafe to continue driving. Otherwise, stopping is prohibited at all times, and that includes not stopping to pick up or set down passengers on a standard clearway. Urban clearways, which operate during specific hours like rush hours, do allow stopping briefly to pick up or set down passengers, but only for a reasonable time and without causing obstruction. Parking or stopping for any other reason is not allowed on clearways, and doing so can result in fines or penalties.
