Preventable Vehicle Accident …..One in which the driver failed to do everything reasonable to avoid the accident
Accident Statistics & Facts 77% of accidents are due to driver error Nearly 6.3 million police-reported motor vehicle crashes occurred in the U.S. last year Large trucks accounted for 9% of the vehicles in fatal crashes Regardless of crash severity, the majority of vehicles in single and two-vehicle crashes were going straight prior to the crash
Accident Statistics & Facts Traffic death rates are 3 times higher at night than during the day 90% of a driver’s reaction depends on vision From 1975-1999, an estimated 123,213 lives were saved by seat belts Every 33 minutes someone dies in an alcohol-related crash
Speeding Accidents Statistics & Facts Speeding was a contributing factor in 30% of all fatal crashes 12,628 lives were lost in speeding-related crashes in 2001 The economic cost of speeding-related crashes is estimated to be $28 billion each year-$53,243 per minute or $887 per second
Speeding Accidents Statistics & Facts Speeding was involved in more than 1/3 of the fatal crashes that occurred in construction/maintenance zones in 2001 86% of speeding-related fatalities occurred on roads that were not Interstate highways Between midnight and 3 am, 76% of speeding drivers involved in fatal crashes had been drinking
CDL Driver Coaching Skills Cushion of Safety Following Distance/Tailgating Covering the Brake Long Distance Scanning Total Stopping Distance
Cushion of Safety Maintain at least a 4-second following distance when traveling (in ideal conditions) under 40 mph; at greater speeds, add 1 second Scan your driving environment at least 12-15 seconds down the road Frequently check both left and right mirrors every 3-5 seconds Scan for other vehicles moving behind your truck before you lose them in your blind spot
Cushion of Safety Cushion of Safety Be aware of driving in others’ blind spot When changing lanes to the right, take extra care in checking your right mirrors for vehicles alongside your truck When backing off in a problem situation, “cover the brake” In congested areas, increase your scanning activity and levels of alertness
Total Stopping Distance Total Stopping Distance = Perception Distance + Reaction Distance + Brake Lag Distance + Braking Distance
Definitions Perception Distance: distance vehicle travels from the time a driver spots a problem to the time it takes them to react (12-15 seconds = ¼ mile or 1 ½ city blocks) Reaction Distance: distance vehicle travels from the time the accelerator is released to the time the brake pedal is pressed
Reaction Distance THE AVERAGE PERSON’S REACTION TIME = ¾ SECOND Traveling at 30 mph ¾ second = 33 feet Traveling at 55 mph ¾ second = 60 feet Traveling at 65 mph ¾ second = 72 feet
Definitions Brake Lag Distance: distance vehicle travels after the brake pedal is pressed and before air brakes actuated Braking Distance: distance from the time after the brake is actuated and before vehicle comes to a complete stop
Adverse Weather Conditions Increase your following distance in fog, heavy rain, snow, ice, etc. Reduce speed to well below the posted speed limit. Braking distances can increase 300% on ice an snow Vehicle weight will not decrease stopping distance Whenever there is a glare on the road, the conditions are prime for hydroplaning and black ice.
Reading The Traffic Situation Driver A should be reading the traffic situation and recognize that if car B or D were to change lanes suddenly, the drivers of B or D might not see truck A in their blind spot
Accident Report The accident report would say: I (driver A) had no one in front or behind me. Car B pulled right out in front of me. I could not do anything about it.
Preventability Standpoint The driver could have done something reasonable to avoid the collision, by moving out of these blind spots.
