Depending on the time of day and location, incidents create 55-60% of the congestion on highways in Nevada.
Identifying the severity and location of a crash can significantly shorten the response and clearance times, it may even save lives.
An accident that occurs as a result of congestion or distraction from a prior crash is referred to as a secondary accident.
Exact figures on the number of secondary accidents are difficult to calculate. Preliminary results of a study by UNLV indicate that as many as 22% of all incidents in the Las Vegas region are the result of an earlier crash.
Secondary crashes can potentially be more serious than the original crash as motorists become impatient and distracted with their driving. National studies show that as many as 18% of secondary crashes result in a fatality.

Welcome to TIM

Effective traffic incident management is vital to the successful operation of modern highway systems in the state of Nevada. By working towards an enhanced level of interagency coordination, collaboration and communication through the activities surrounding an active coalition of traffic incident management stakeholders there is a proven difference in roadway clearance times, enhancing safety and decreasing the number of crashes, even fatalities.

City and county boundaries are not contained by traffic, congestion knows no boundaries. As such, efficient performance of traffic incident management practices has increased in complexity, requiring technology and a well-planned, coordinated, multi-disciplinary response.

Traffic Incident Management activities involve:

  1. Quick detection of highway incidents through video detection, loops or 911.
  2. Verification of highway crashes (CCTV Cameras, monitors, etc.).
  3. Timely response to the crash or incident by a plethora of incident responders including city, county and state: law enforcement, fire & recovery, public works, engineers, maintenance, private ambulance, EMT, towing companies, freeway service patrol among others.
  4. Efficient methods for clearing incidents quickly (incentive towing programs, legislative measures that support authority removal and move-it laws allowing vehicles involved in non-injury crashes to move out of travel lanes).
  5. Restoration of traffic flow back to its pre-incident capacity as quickly as possible.
  6. TIM performance measures to be implemented throughout the state of Nevada so that the benefits of safe, quick clearance can be demonstrated.
  7. Timely and accurate information delivered to the traveling public through a variety of communications avenues like media, public information officers, PSAs, internet, real time travel time delivery mechanisms (i.e., smart phones), social media and other tools including NDOT 511 program.


Although Average Vehicle Miles Traveled (AVMT) rose 6 million miles from 2013-2017, a decline in fatal crashes trend continued through 2019!  This is in no small part the result of the statewide safe, quick clearance activities practiced by all first responders!  60.3% of all first responders involved in clearing crashes and traffic management activities have all received the same training. Over 4900 of Nevada’s responders have participated in TM SHRP2 Multiagency Training, presented through the TIM Coalition certified trainers.

All agencies also follow the Nevada Statewide Open Road Policy, signed by NDOT, DPS and the Governor and supported by the Nevada TIM Guidelines.  Kudos to Nevada’s AMAZING incident responders for saving lives!

Nevada Legislative Initiatives Supporting Traffic Incident Management:

Senate Bill 312 was signed by Governor Brian Sandoval in May 2017. This important legislation strengthens several TIM-related laws, including the requirement for cars to move over or slow down for emergency vehicles, requirements for motorists to move cars from the travel lanes after a crash if possible, and vehicle removal laws.  The legislation went into effect on October 1, 2017. You can read the legislation here: Senate Bill 312

Nevada TIM Coalition Video Production

On Saturday, June 2, 2018, Nevada TIM Coalition partners partnered to produce this video that will be used to promote traffic incident management across Nevada. This video is being shared with agencies to help explain and promote TIM principles.
