Case Study Information: An accident occurred in which Driver 1 turned right from Post Road onto the eastbound lane of Route 460. Driver 2 was approaching this same intersection on Route 460 traveling east. Driver 2 swerved left to avoid hitting Driver 1, passing driver 1, and then stopping ahead of driver 1. Driver 1 passed the now stopped car of Driver 2 and pulled onto the shoulder of Route 460 east of Driver 2. Police arrived and details for the accident were gathered. Driver 2s car stopped a distance of 325 feet east of Post Road. Driver 1 stopped 50 feet east of Driver 2s car. Driver 1s car was a 2018 Jeep Grand Cherokee. Driver 2s car was a 2018 Honda Fit. Road conditions were dry, the road at this point is straight and level. No other cars were affected by the incident. Driver 1 said he pulled out while Driver 2 was still some dis
tance west of the intersection and that Driver 1 had accelerated to 50 MPH before Driver 2 swerved around him, evidently going well over the speed limit for Route 460, which is 60 MPH. Had Driver 2 not been speeding, he would have been able to slow and not swerve. Driver 2 said he was driving at 60 MPH and Driver 1 pulled onto Route 460 when Driver 2 was only 2 car lengths from the intersection, forcing Driver 2 to swerve to avoid a collision. Driver 1 had barely started to accelerate and could not have been going 50 MPH when Driver 2 had to swerve around Driver 1. He started his swerve one car-length behind Driver 1 and started to stop when he was one car-length in front of Driver 1. It may be useful to do calculations in units of feet/second rather than miles/ hour. The conversion rate is 1 MPH = 1.467 ft/s so 50 mph = 73.3 ft/s and 60 mph = 88 ft/s.
