Facts: OnJune 1, 2016, at3 p.m., Justin Mitchellturned his Ford Escort from southbound Russell Avenue so that he was traveling westbound on a two-lane highway, Maryland Avenue, in Gaithersburg, Maryland. Maryland Avenue has one lane of traffic in each direction. However, only one car can pass at a time when cars are parked on both sides of the road. Suddenly, Justin felt a sudden, jarring impact as the front left bumper of a blue Honda Accord, driven by Mary Myer, struck the right front of his Ford.

Mary's vehicle struck Justin'scarwith such force that Justin was thrown forward and backwardinside his vehicle so that his head crashed into his headrest and his left hand struck the driver'sinside window. The front bumper of Mary's Honda struck the front of Justin's vehicle so that it crushed the right side of the Ford's front bumper against the right front tire and pushed the car into a lamppost. It was impossibleto drive the Ford, so it was towed from the scene byBig Bill's Body Shop.

Montgomery County Police OfficerFreddy Friendly arrived at the scene within20 minutes of the collision. Soon, other police officers arrived, and Mary gave one of the officers her driver's license, vehicle registration, and insurance card. Her insurance card showed that she had personal injury protection for $2,500 and collision coverage with a $500 deductible. Mary also had bodily liability coverage for $20,000 per person/$40,000 aggregate with theGeckoInsurance Company effective untilNovember 15, 2016.

At the scene, Justin complained to OfficerFriendly that hishead, neck, and lefthandhurt. The officer immediately summoned an ambulance.

While he was waiting for the ambulance, Justin gave the officer his version of how the collision occurred. Justin said that cars were parked on both sides of the road so that he was only able to travel 20 miles per hour as he traveled in the westbound lane of Maryland Avenue and approached the stop sign at the intersection of Highland Avenue. Even though his view was partially blocked by a large white van that was parked on the right side of the road immediately before an alley, Justin thought he saw a blue car entering Maryland Avenue from the alley to his right. Justin continued along Maryland Avenue without braking because he expected the blue car to stop before entering the roadway. Justin did not see the blue car stop. However, as Mary's vehicle struck Justin's car, he noticed that she was not looking in his direction.

After he spoke with Justin, the officer interviewed Mary, who gave a different version of the crash. Mary claimed that she stopped her vehicle at the end of the alley when she arrived at Maryland Avenue so that she could determine if it was safe to turn left onto Maryland Avenue. Mary admitted that her view of the roadway was partially blocked by a large white van parked to her left on Maryland Avenue. However, Mary indicated that she did not enter Justin's lane of traffic even though she inched the front of her vehicle into Maryland Avenue until it was even with the left side of the parked white van. She claimed that Justin lost control of his vehicle so that it skidded, and the right front of the Ford struck the left front of her car where it was fully stopped, waiting to enter Maryland Avenue.

Officer Friendly gave Mary a traffic ticket for failure to yield the right of way. Justin was rushed to Shady Grove AdventistHospital by ambulance. Upon arrival at the hospital,Justin received emergency outpatient treatment that included a physical examination, three cervical x-rays, and two lefthand x-rays. The x-rays were obtained by a radiologist employed by Drs. Crack and Bone, P.C.
