Safety and Security Standards

This guide contains instructions for driving on the Non-Movement Areas as defined by the movement area boundary. (See Appendix A Danger Never Cross a Solid Yellow Line). All drivers will use this guide to ensure security and safety procedures are known and followed. This guide is not all inclusive and should be followed in addition to all other requirements established by the Airport Rules and Regulations, the City of Twin Falls, the State of Idaho, and the US Department of Transportation.

ENTERING THE AOA (Airport Operations Area)

The AOA (Airport Operations Area) is defined as the area within the perimeter fence of the airport. The Airport Badging Office creates access credentials required to enter the gates. To access the AOA, you will use the card reader/keypad to open the gate. If you are a badge holder, place your badge within a 2” proximity of the card reader. If you have been given a temporary Unique PIN, enter your PIN with the keypad.

Vehicle Access Gate Rules:

  1. Stop the vehicle beyond the white bar on the asphalt.
  2. DO NOT PERMIT another vehicle to enter behind you. (Piggybacking)
  3. Wait for the gate to fully close while entering or exiting.
  4. Up to two (2) vehicles may be sponsored through a gate at one time. The sponsor is responsible for ensuring compliance with the escort procedures listed below.
  5. Multiple vehicles may leave at the same time, the last vehicle is responsible for remaining at the gate until it closes.
  6. Immediately report any violations to the Airport Security Coordinator at 208.731.4051, or Airport Operations at 208.308.7315, or call 911 if an emergency response is needed.

Accessing the AOA (Airport Operations Area) Through a Tenant Owned Building:

  1. Building Owners are responsible for securing AOA access through their buildings.
  2. Authorized users may be permitted access through tenant owned buildings.
  3. Authorized users without badges (ex. Transient Pilots, GA Passengers, and Emergency Response Personnel) must be verified by the Tenant prior to being permitted access to the AOA.

Escort Procedures:

  1. Each Badge Holder may escort up to 6 unbadged people, or two vehicles with a combined total of no more than 6 passengers. All vehicles under escort will be accompanied by their sponsor while entering and exiting the AOA (Airport Operations Area).
  2. Escorted persons must be within audible and visual control of the Badge Holder.
  3. A person who has failed an STA (Security Threat Assessment) or CHRC (Criminal History Records Check) may not be escorted.

Appendix B


DO NOT CROSS the Movement Area Boundary line unless escorted by someone with Movement Area Driving privileges.


All vehicle drivers will obey the directions provided by airport staff. Maximum speed limit on the AOA is 15 MPH. Drivers should reduce speeds as conditions dictate, especially around aircraft or in crowded situations.

Yield to pedestrians and all moving aircraft, including aircraft under tow. All vehicles shall give way or pass to the rear of taxiing aircraft and no vehicle shall approach closer than 100 feet of any aircraft when aircraft engines or propellers are in motion.

Stop at all intersections in the hangar areas and check for aircraft traffic. Watch especially when entering the aircraft parking ramp from the hangar area. Some aircraft, such as the agricultural spray planes, have limited forward visibility when moving on the ground.

If the driver must leave a vehicle, he or she will ensure the vehicle parking brake is set and will take any other steps necessary to ensure the vehicle will not roll while unattended.

The following procedures are not required but are recommended to provide an extra margin of safety.

  • Do not approach closer than 10 feet to an aircraft without a spotter.
  • Beware of jet blast behind jet aircraft with the engine running.
  • Avoid using reverse gear. Always try to plan your approach to an aircraft so that you can continue forward
    when ready to leave.
  • More best practices can be found here:


  • Badges are the property of the Airport.
  • Badge Holders must report lost or stolen badges to the ASC and/or their Authorized Signatory immediately.
  • Badge Holder must request escort privileges and movement area or non-movement area driving privileges during the application process.
  • Applicants will be required to complete training before a badge is issued.


Any individual found in violation of the above rules will be subject to the following disciplinary action:

  • Strike 1 – At the Airport’s discretion, a verbal warning will be issued and documented depending on the severity of the offense.
    • Example – A Tenant is seen engaging in reckless driving or unsafe behavior while operating a motor vehicle on airport property, this could warrant immediate suspension and/or revocation of credentials.
  • Strike 2 – Immediate temporary suspension of credentials until re-training is completed.
  • Strike 3 – Immediate suspension, permanent revocation considered following a review and appeals process.
