Highway Traffic Safety Administration have called for a Driver Alcohol Detection System for Safety (DADSS) program to put alcohol detection devices in all cars. Blind spot monitor involves cameras that monitor the driver's blind spots and notify the driver if any obstacles come close to the vehicle. Blind spots are defined as the areas behind or at the side of the vehicle that the driver cannot see from the driver's seat. Blind-spot monitoring systems typically work in conjunction with emergency braking systems to act accordingly if any obstacles come into the vehicle's path. A rear cross traffic alert (RCTA) typically works in conjunction with the blind spot monitoring system, warning the driver of approaching cross-traffic when reversing out of a parking spot. Driver drowsiness detection aims to prevent collisions due to driver fatigue. The vehicle obtains information, such as facial patterns, steering movement, driving habits, turn signal use, and driving velocity, to determine if the driver's activities correspond with drowsy driving. If drowsy driving is suspected, the vehicle will typically sound off a loud alert and may vibrate the driver's seat. Driver monitoring system is designed to monitor the alertness of the driver. These systems use biological and performance measures to assess the driver's alertness and ability to conduct safe driving practices. Currently, these systems use infrared sensors and cameras to monitor the driver's attentiveness through eye-tracking. If the vehicle detects a possible obstacle, it will notify the driver and if no action is taken, the vehicle may react to the obstacle. Electric vehicle warning sounds notify pedestrians and cyclists that a hybrid or plug-in electric vehicle is nearby, typically delivered through a noise, such as a beep or horn. This technology was developed in response to the U.S. National Highway Traffic Safety Administration ruling that issued 50 percent of quiet vehicles must have a device implemented into their systems that sound off when the vehicle travels at speeds less than 30 km/h (18.6 mph) by September 2019. Forward collision warning (FCW) monitor the speed of the vehicle and the vehicle in front of it, and the open distance around the vehicle. FCW systems will send an alert to the driver of a possible impending collision if gets too close to the vehicle in front of it. These systems do not take control of the vehicle, as currently, FCW systems only send an alert signal to the driver in the
