![]() ![]() Air travel dominates a frequent traveller’s individual contribution to climate change. The first is the disconnect between its role in our personal and collective carbon emissions. This research is available here.Flying is a highly controversial topic in climate debates. Of specific interest are those that occurred in single-vehicle rollovers. In 2008, NHTSA published a Research Note providing a descriptive assessment of fatalities of occupants of 15-passenger vans using 1997-2006 Fatality Analysis Reporting System data. With nearly 11% of fatal 15-passenger-van rollover crashes attributed to tire failure, the TPMS safety standard proves to be a significant safety advancement for these vehicles. The TPMS then warns the driver of the issue. The safety standard applies to vehicles weighing 10,000 pounds or less, including buses and 15-passenger vans, and requires manufacturers to install a four-tire TPMS that detects whether a tire is more than 25% underinflated. That same year, NHTSA established a new safety standard requiring tire pressure monitoring systems (TPMS) for light vehicles to help prevent tire failure (Federal Motor Vehicle Safety Standard No. Previously, rollover had been proven to be one of the most significant dangers for 15-passenger vans, with the risk increasing dramatically as the number of occupants increased from fewer than 5 to more than 10. Under Title X, Subtitle C, Section 10309 of the law, Congress directed the Secretary of Transportation to require testing of 15-passenger vans as part of NHTSA’s NCAP rollover resistance program. The Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU) was signed into law on August 10, 2005. It also requires additional reliance on the side-view mirrors for changing lanes. Size: A 15-passenger van is substantially longer and wider than a car, and thus requires more space to maneuver.See the vehicle owner’s manual for maximum weight of passengers and cargo and to determine towing capability. Cargo: Cargo should be placed forward of the rear axle avoid overloading the van or placing any loads on the roof.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. Occupancy: Never allow more than 15 people to ride in a 15-passenger van.The last four digits of the TIN indicate the week and year the tire was made (e.g., 1010 = March 2010). Check a tire’s age by finding its Tire Identification Number (TIN) on the tire’s sidewall. Used 15-passenger vans may come with dangerous spare tires that are many years old. ![]() ![]() Spares: All tires weaken with age-even unused tires avoid using an old spare on your 15-passenger van.Recommended tire pressure may be different for front and back tires. Check the driver’s side door pillar or the owner’s manual for the recommended tire size and pressure. ![]() Excessively worn or improperly inflated tires can lead to a loss of vehicle control and possibly a rollover. A van’s tires, including the spare tire, need to be properly inflated and the tread should not be worn down.
