A commercial driver's license is ideal. It's important to know that 15-passenger vans handle differently than cars, especially when fully loaded. ATTENTION Stay focused on the task of safe driving by being well rested, never using a handheld phone at the wheel, and limiting conversation with other passengers. Drivers shouldn't drive more than 8 hours per day. SPEED Always obey the posted speed limit, and reduce your speed as needed based on road or weather conditions. Remember that 15-passenger vans require additional braking time and cannot handle abrupt maneuvers the way cars can. for the recommended tire size and pressure. Recommended tire pressure may be different for front and back tires. SPARES All tires weaken with age-even unused tires; avoid using an old spare on your 15-passenger van. Used 15-passenger vans may come with dangerous spare tires that are many years old. Check a tire's age by finding its Tire Identification Number (TIN) on the tire's sidewall. The last four digits of the TIN indicate the week and year the tire was made (e.g., 1010 March 2010).
