Serious US 75 Crashes in Allen Require Careful Investigation

Potentially important evidence may include:
Dashcam footage
Traffic or surveillance video
Witness statements
Photographs and video from the crash scene
Vehicle event data recorder information
Speed and braking data
Physical vehicle damage
Tire marks and roadway debris
Cell-phone records when legally relevant
Police and emergency-response records

TxDOT also maintains the state's crash-reporting system, where qualifying law-enforcement crash reports are submitted after collisions involving injuries, deaths, or sufficient property damage.
What Can Cause a Highway Crash Near Exchange Parkway?

Depending on the evidence, investigators may examine factors such as:
Distracted driving
Excessive speed for traffic conditions
Following too closely
Unsafe lane changes
Failure to maintain control
Sudden congestion
Commercial vehicle involvement
Mechanical or tire problems
