Which of the following actions is illegal in Maryland while driving?

Answer: C — Using a handheld mobile device

Using a handheld mobile device while driving is illegal in Maryland due to strict laws aimed at reducing distractions for drivers. The law is designed to promote safer driving conditions by discouraging the use of devices that require a driver's hands or attention. Using a handheld mobile device significantly increases the risk of accidents, as it diverts focus away from the road and impairs the ability to react promptly to changing traffic situations. In contrast, activities such as using a hands-free device, adjusting the radio station, or eating while driving, while potentially distracting, are not categorically banned under Maryland law. However, it is essential to approach all distractions with caution, as they can still contribute to unsafe driving behaviors.
