$15-$PASSENGER VAN SAFETY NHTSA's TOp Safety Recommendations for $15-$Passengervanuse

EXPERIENCE Fifteen$-$passenger vans should only be driven by experienced, licensed drivers who operate this type of vehicle on a regular basis. 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.

SEAT BELTS All occupants need to wear seat belts at all times. Inspect seat belts regularly and replace any missing, broken, or damaged belts and$/$or buckles. An unrestrained $15-$passenger$-$van! cccupant involved in a single$-$vehicie c:st$.$ is aporoximately four times more likely to $!?$ occupant. the spare tire, need to be ple. $....0\mathrm{.}4$ of vehicle control and possibiy $2$ solover. Check the driver's side door pillar or the owner's manual

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 $2010).$

OCCUPANCY Never allow more than $15$ people to ride in a $15-$passenger van. Fill the seats from front to back: when the van is not full, passengers should sit in seats that are in front of the rear axle.

CARGO Cargo should be placed forward of the rear axle; avoid overloading the van or placing any loads on the roof. See the vehicle owner's manual for maximum weight of passengers and cargo and to determine towing capability.

SIZE $A15-$passenger van is substantially longer and wider than a car, and thus requires more space to maneuver. It also requires additional reliance on the side$-$view mirrors for changing lanes.
