Increased the risk of run-off-road crashes by 35 percent. Police crash data from 25 states between 2009 and 2015 for vehicle models where the systems were sold as optional reduced rates of single-vehicle, sideswipe, and head-on crashes by 11 percent, and injuries in such crashes by 21 percent. List shows up to 2015 model year. Policies regarding in-car entertainment systems are less developed than cell phone usage laws regarding similar distractions in cars. In the United States, 10 states, D.C., Guam, and the Virgin Islands prohibit all drivers from using handheld cell phones while driving. Additionally, 39 states, D.C., Guam, and the Virgin Islands ban text messaging for all drivers. Charlie Klauer, a researcher at the Virginia Tech Transportation Institute, says that drivers who look at screens have a much higher risk of crashing. Lane departure warning systems combine prevention with risk reports in the transportation industry. The CHMSL is intended to provide a warning to drivers whose view of the vehicle's left and right stop lights is blocked by interceding vehicles. The 1918 Stutz Bearcat had a central throttle pedal with the clutch and brake to the right and left. Markings covered in snow or old lane markings left visible can hinder the ability of the system.
Tesla uses the most advanced lane assist system (kind of LKA) combined with their adaptive cruise control system marketed together as 'Autopilot'. Some vehicles combine adaptive cruise control with lane keeping systems to provide additional safety. By providing safety managers with driver- and fleet-risk assessment reports and tools, it facilitates proactive coaching and training to eliminate high-risk behaviors. Latest models of In-car entertainment systems are coming equipped with rear-view cameras along with side cameras for better safety. However, few states have developed laws to limit the content that drivers can view on in-car entertainment systems. The system doesn't provide a warning, rather, it can prevent a crash from occurring at speeds between 3.6 and 30 km/h (2.2 and 18.6 mph). Most systems do not allow the use of the cruise control below a certain speed - typically around 25 or 30 mph (40 or 48 km/h). In 2020, UNECE released an automated lane keeping system (ALKS) regulation which include features such as lane-keeping and adaptative speed for specific roads up to 60 km/h. This is because of the limitations associated with the lane-keeping feature. Lane keeping assist (LKA) is a feature that, in addition to the lane departure warning system, automatically takes steps to ensure the vehicle stays in its lane.
Lane departure warning systems also face many legal limitations regarding autonomous driving. The system does not take into account other vehicles on the road and "cannot replace good driving habits". The same year, Cadillac introduced an integrated vehicle handling and software control system called the Integrated Chassis Control System (ICCS), on the Cadillac Eldorado. Lane departure warning systems biggest limitation is that it is not in complete control of the vehicle. The sample size was not large enough to control for demographic and other variables. Generally, trade-in vehicles must get a weighted combined average rating of 18 or fewer miles per gallon (some very large pickup trucks and cargo vans have different requirements). Lane keeping assist is mandatory for new cars and vans in the European Union as of 2022 under the name Emergency Lane Keeping System. Fiat is launching its lane keep assist feature based on TRW's lane keeping assist system (also known as the haptic lane feedback system). The neural network then will be able to change the steering angle based on the lane change on the road and keep the car in the middle of the lane.
Vehicle companies often use the term "lane keep(ing) assist" to refer to both reactive lane keep assist (LKA) and proactive lane centering assist (LCA) but the terms are beginning to be differentiated. Vehicle location information can also be used to verify that legal requirements are being met: for example, that drivers are taking rest breaks and obeying speed limits. The lane keeping assist system is being achieved in modern vehicle systems using image processing techniques called Hough transform and Canny edge detection techniques. This system integrates the lane-detection camera with TRW's electric power-steering system; when an unintended lane departure is detected (the turn signal is not engaged to indicate the driver's desire to change lanes), the electric power-steering system will introduce a gentle torque that will help guide the driver back toward the center of the lane. The Eagle's thick viscous fluid center differential provided a quiet and smooth transfer of power that was directed proportionally to the axle with the greatest traction.

The only toll facility that still accepts cash is the South Bay Expressway in San Diego County, but it uses unstaffed toll booths with cash machines that require exact change.
