When is it illegal to drive into an intersection?

Driving into an intersection when there is not enough space to turn right is illegal because it can lead to obstructing traffic and creating hazardous situations. When a driver enters an intersection but cannot complete the turn, they may block other vehicles and create gridlock, leading to potential collisions or delays for all vehicles involved. It is vital for drivers to ensure that there is sufficient space on the other side of the intersection to complete their maneuver safely before entering. This rule helps maintain the flow of traffic and ensures the safety of both the driver and other road users.

In contrast, entering an intersection when the signal is green is permissible as it indicates a clear directive to proceed. Being in a hurry does not justify entering an intersection unsafely, nor does the presence of other vehicles automatically make it illegal to enter as long as the driver behaves according to road regulations.
