Where is it legal to mount phones or communication devices in a vehicle?

Mounting phones or communication devices in a vehicle must adhere to certain safety regulations to ensure driver attention is not compromised. The correct choice indicates that in a car, it is permissible to mount devices virtually anywhere except in the driver's direct line of sight in the middle area of the vehicle. This regulation is designed to minimize distractions while driving.

Having devices mounted outside of this central zone allows easy access for the driver while ensuring that they can keep their focus on the road ahead. The other options provide more restrictive interpretations that do not align with the broader allowances for safe device placement in cars. In particular, limiting placement to the glove compartment or only on the dashboard could hinder functionality, while the restriction for motorcycles only to the handlebars does not account for diverse mounting preferences that maintain safety and accessibility.
