Names differ

NHTSA says that when shopping for a vehicle, you may notice that "different manufacturers use different names for the technologies." We use NHTSA's names.

Warn or act

NHTSA says "some driver assistance technologies are designed to warn you if you're at risk of an impending crash, while others are designed to take action to avoid a crash."

Forward collision warning

NHTSA says forward collision warning "Detects a potential collision with a vehicle ahead and provides a warning to the driver." It says these systems "only provide a warning to the driver and do not take action to avoid a crash."

Who is driving

For Levels 0 to 2, NHTSA says: "You, as the driver, are responsible for driving the vehicle." It says Level 3 to 5 technologies are not available on today's vehicles for consumer purchase.

Your owner's manual

NHTSA says: "Be sure to review your vehicle's owner's manual for more information on your vehicle's technology and safety features."

After glass work

We do not say whether any vehicle needs calibration after glass work. Follow your vehicle maker's instructions and owner's manual. Our calibration guide has more.
