In case the bus driver has to make an emergency stop, what is the first action they should take?

The first action a bus driver should take in case of an emergency stop is to activate the hazard lights. This action is crucial as it alerts other drivers and road users that the bus is experiencing an emergency situation. Activating hazard lights helps increase visibility and can prevent further accidents by warning others to proceed with caution.

Once the hazard lights are activated, the bus driver can then follow up with additional actions, such as pulling over to the side of the road or checking mirrors to assess the situation and ensure that the bus can be stopped safely. However, the primary concern during an emergency is to notify others promptly, making the activation of the hazard lights the most immediate and vital first step.
