• What should you do if you have a blow out? What order?
• Grip steering wheel firmly/ease up on gas/check traffic situation/pull of the road/put flashers on/find a safe place to stop
• Braking hard may cause the vehicle to swerve

Brake Failure
• What should you do if your brakes fail?• Pump the brake pedal/downshift/pull parking

Accelerator Malfunctions• What do you do if your gas pedal stays flat on
the floor because of a broken spring?• Shift to neutral/check traffic/brake safely to the
side of the road• What do you do if your gas pedal is stuck
(doesn't return to idle speed)?• Kick side of pedal to set free/apply the
brakes/choose an escape path/shift to neutral if in a curve
• Turn of ignition

• How can we minimize the effects of a collision?• Keep control of your vehicle• Change speed or direction• Steer for something soft• Brake or accelerate in the case of side impact• Honk horn• Flash break lights / release brakes on impact
(rear end type)
