Common Road Hazards

Road Signs

  • In an estimated 787,236 intersection-related crashes, about 52 percent of the vehicles were traveling on roadways that were controlled by at least one traffic signal/sign
  • 29 percent of multi-car collisions at intersections were classified as “failure-to-yield” crashes where one of the involved drivers failed to yield the right-of-way at a traffic signal
  • 21 percent of motorists violate the “No Turn on Red” signs if given the opportunity

Stop Signs

  • In an estimated 787,236 intersection-related crashes, about 31.3 percent of the vehicles were traveling on roadways that were controlled by at least one stop sign
  • False assumption of another’s action was found to be the most significant critical reason for turning-right crashes at stop sign
  • In intersections controlled by stop signs, an average of 2,967 fatalities occurred each year with about 45 percent attributed to the driver failing to obey the sign

Stop Lights

  • Each year in the United States, running red lights is the top cause of car accidents, resulting in nearly 1,000 wrongful deaths and about 90,000 cases of bodily injury.
  • Red lights are designed to help ease the traffic flows that could get congested by four-way stop signs and blinking lights, however 56 percent of drivers admit to running red lights
  • According to the National Highway Traffic Safety Administration, more often than not drivers are reported to speed up when approaching a yellow light rather than slow down


  • At intersections, the biggest cause of cars colliding with pedestrians comes from drivers making a permissive left turn across the crosswalk with the “walk signal”
  • More than a quarter of fatal crashes involving pedestrians are the result of pedestrians disobeying intersection traffic control or making misjudgments while attempting to cross a street
  • All intersections are not treated equal when it comes to “marked” or “unmarked” crosswalks. Drivers may be more likely to stop and yield to pedestrians in marked crosswalks compared to unmarked crossings


  • Between 65 percent and 83 percent of all fixed objects involved in roadside crashes are located behind a driveway or intersection
  • Intersection-related crashes are almost 335 times more likely to occur if the driver turns with an obstructed view from a planted object such as a tree, bush, telephone pole etc.
  • 50 percent of deaths involving collisions with fixed objects in 2010 involved a vehicle striking a tree. Utility poles were the next most common objects struck, accounting for 14 percent of fatalities

Other Cars

  • In the estimated 2,188,969 total vehicle collisions crashes 36 percent were attributed to on or more vehicles turning or crossing at intersections
  • On average each year, there are 1,578 fatalities in two-vehicle crashes in intersections
  • A large proportion of the fatalities in two-vehicle crashes occurred to the passengers of the cars that were struck rather than to the passengers of the vehicle that did the striking


  • Each year, on average, more than 4,000 pedestrians are killed in the United States
  • 24 percent of pedestrian fatalities occurred at intersections
  • In 2009, pedestrian deaths accounted for 12 percent of all traffic fatalities in motor vehicle traffic crashes


  • The 630 cyclist deaths in 2009 accounted for 2 percent of all traffic fatalities during the year
  • Of the bicycle accidents involving a collision with a car, 45 percent take place in intersections
  • If a collision occurs when a driver pull out into an intersection from a stop sign when a cyclist had the right of way, the driver of the vehicle will be at fault This instance accounts for almost 10 percent of all intersection accidents with cyclists
