Stopped Traffic, Hot Engine, and a Tempting Shoulder
On a 95°F afternoon, Maya rides an air-cooled 500 cc motorcycle south on I-65 near Indianapolis with a passenger. Traffic stops for a crash. Her engine temperature warning light comes on after 10 minutes of idling. The right shoulder is about 10 feet wide, littered with tire tread and gravel, and other motorcyclists begin riding it toward the next exit, 1/4 mile ahead. The next exit after that is 2 miles away. Her passenger is hot and anxious. Lane filtering between the stopped cars would move them forward, but the lanes are narrow. She sees a state trooper two cars ahead. Both wear DOT helmets and gloves, but they have no water. She must choose a legal and safe action and manage the overheating engine.
1. Is riding the shoulder or filtering between lanes legal in Indiana? What should Maya do instead?
Read the worked answer
Neither option is legal in Indiana. Lane splitting or filtering between moving or stopped traffic is not authorized, and the shoulder is not a travel lane; riding it to bypass traffic can bring a citation and puts her near debris, stopped vehicles, and the trooper. The fact that other motorcyclists are doing it does not make it lawful. Because the engine is overheating, she may use the shoulder only to stop safely if necessary-not to continue down the highway. She should signal, move as far right as is safe, stop, shut the engine off, and let it cool. She should not ride the shoulder 1/4 mile to the exit. If traffic begins moving, she can rejoin when safe; otherwise, waiting or using a legal exit route is the safer choice.
2. How should she manage heat, the passenger, and the engine while waiting?
Read the worked answer
With the engine off, Maya should move herself and the passenger to a safer spot away from the traffic lane if possible, drink water, and shade themselves. She should not open the radiator cap while hot. She should let the bike cool, check for obvious leaks or a failed fan, and restart only when safe. Idling in 95°F heat with no airflow is what pushed the temperature up, so once moving again she needs airflow and a clear destination. If the warning persists, she should not continue; overheating can warp heads and seize an engine. She should also watch the passenger for heat illness and be willing to abandon the ride. The legal and safe plan is to stop, cool down, and rejoin or exit legally-not to filter or shoulder-ride.
