To signal for help, a driver parked on a roadside should not do which of the following?

When a driver is in need of assistance and is parked on a roadside, standing on the roadway and waving their arms can be extremely dangerous. This action places the individual at risk of being hit by oncoming traffic, as it creates a situation where they are not only visible but also directly in the path of vehicles. In contrast, using emergency flashers, calling for help using a phone, or raising the hood of their vehicle are all safer and more effective methods for signaling for assistance. Emergency flashers alert other drivers to the presence of a stationary vehicle, while raising the hood is a common signal indicating mechanical trouble. Using a phone to call for help allows the driver to stay safely inside their vehicle until assistance arrives. Therefore, standing on the roadway poses an unnecessary risk and should be avoided.
