Airing on Saturday, March 14 on ABC

Is your life at risk every time you buckle up? From road-side snipers to cost-cutting redesigns of guardrails to reckless truckers, "20/20" reports on life and death on the American road. "20/20" airs on SATURDAY, MARCH 14 (8:00-9:00 p.m., ET) on the ABC Television Network. (OAD: 9/19/14) Reports include:

· The Hunt for the Kansas City shooter: This spring, motorists in the Kansas City area had to cope with much more than rush hour traffic - a lone gunman was firing at vehicles on the highway, nine times in all. Once police determined they had a serial shooter on their hands, they deployed a series of sophisticated and controversial investigative techniques to move from a series of random data points to the arrest of suspect Mohammed Whitaker and his green Dodge Neon.

· Hazardous Guardrails?: Brian Ross investigates a major manufacturer of highway guardrails accused of making a design change that has caused these accident cushions to become lethal lances in some gruesome accidents.

· Truckers: In the wake of the Tracy Morgan fatal crash, more questions than ever are popping up about fatigued truckers and the safety of those massive rigs on the road. Matt Gutman talks to a trucker who reveals the pressures companies put on drivers to stay on the road, and he shares video of his own dispatchers telling him to keep driving even though he is complaining that he is falling asleep at the wheel. Additionally, "20/20" sets up our own speed trap with the Ohio HP and catches lead footed truckers in the act.

"20/20" is anchored by Elizabeth Vargas and David Muir. David Sloan is senior executive producer.
