The speed limit should be 25 mph (40 km/hr) or below throughout the ECF to protect
security personnel and to minimize the potential for accidental impact with vehicle
barricades. This speed limit also applies to the outbound lanes as they approach the
vehicle barricades. Any deployed active vehicle barrier system has the potential to be
lethal. Limitations on the maximum speed serve to reduce the potential for injuries or
fatalities.

Signage
Prepare a comprehensive signage plan for each ECF that is compatible with the
installation's signage program and complies with local standards. The plan should
include the following types of signs.
Traffic Regulatory and Directional Signs, which control traffic flow and direct
vehicles to specific gates, ID check lanes or the Visitors Center.
Entry Control Procedures Signs, which explain current ID check procedures for
drivers; display of current FPCON status should follow Service guidelines.
Variable Message Signs (VMS) at the ECF that provide the ability to inform
motorists of roadway status or other general information per Traffic Engineering
and Highway Safety Bulletin: Traffic Engineering for Better Gates. Locate
these signs inside the installation and at least 200 ft (61 m ) beyond the ID
check area.
Warning signs, markings, object markings and delineators indicate hazards to
users.
These signs will reduce conflict between approaching vehicles and improve the flow of
traffic through the ECF. Minimize the use of signs to prevent the obstruction of the lines
of sight for security personnel. When signs are required they should be located to
provide the least obstruction to the lines of sight of security personnel.
Provide signage in accordance with Service regulations and the MUTCD. Additional
information on the standard size and shapes of markings and signs can be found in the
latest edition of the Federal Highway Administration's Standard Highway Signs.
Examples of signage, which could be used in an ECF, are provided below. Use of signs
should be consistent with the MUTCD. Sign designations in accordance with the latest
edition of the Standard Highway Signs are provided in parentheses.
