In the USA, slow down and move to the right side of the road as soon as it is safe to do so. On a 2-lane road, move to the shoulder. Allow the emergency vehicle to proceed.

yield to the emergency vehicle
An emergency vehicle is any vehicle that is authorized to respond to an emergency. Most emergency response vehicles are easy to see and hear because they are fitted with visual and audible warning devices.
If you hear a siren close by but cannot see the emergency vehicle you should follow the law in your jurisdiction, which generally is to pull over safely until you are able to determine that you are not in its path.When being approached by an emergency vehicle using sirens and light/s, state laws in the U.S. generally require motorists to immediately pull to the right side of the road and wait for the emergency vehicle to pass. If stopped at an intersection with two-way traffic, remain stopped until the emergency vehicle passes.
While it is perfectly legal in Texas to do so, as a driver, you must be aware of your surroundings - if both ears are covered by the headphones, you will not be able to hear sirens of approaching emergency vehicles. Driving is a serious responsibility, and a privilege, not a right!! When driving, one needs to concentrate on the road.
Figure out where the siren is coming from and get out of the way of the emergency vehicle by pulling over or moving out of the way.

Move to the right side of the road to allow emergency vehicles to pass safely. Continue walking in the same direction but stay alert for any approaching vehicles. Do not suddenly change your direction or stop abruptly.
