Subject: Accelerator Stuck & Can't Stop Vehicle Protocol

Due to recent cases of uncontrollable acceleration in certain vehicle makes and models, and the ability of car occupants to call 911, 999, 000, 112, etc., for help, the Academy has rapidly but carefully developed a protocol to assist the Emergency Dispatcher if confronted with the caller so involved - whether the caller is the driver or a passenger. While we know that the occurrences of such cases with someone involved able to call may be rare, to date, we know of two such cases - in one of which the outcome was tragic.

Obviously for the communication center to be involved and help the caller in these instances, such an event requires the coming together of several factors: having a phone to call with, the ability to call, have the time to call, a linear roadway space ahead, presence of traffic congestion, and vehicle speed.

Special Non-MPDS Use Statement

* Any emergency communication center, whether an MPDS user or not, can use the printed protocol card under a special limited use license contained within them. However, they cannot be incorporated into any 3rd party products or CADs, modified in any way, or re-distributed for any other uses. The user must keep all such materials and protocols up-to-date per postings on this site or by contacting the IAED.

This new protocol is currently available only in manual card format (tabbed pullout style). We are working to imbed it into the ProQA software (as an always accessible icon button) in the immediate future. This protocol can be used by calltakers in all three disciplines - Police, Fire, and Medical.

This Protocol's use is not dependent on the version or type of the Priority Dispatch System you currently have, although for safety and standard of care and practice correctness, the Academy urges you to be on manual v12.0 (Medical), v5.0 (Fire), and/or v3.0 (Police) and/or ProQA logic version builds dated no earlier than: v12.0 (Feb 2010), v5.0 (Feb 2010), v3.0 (April 2009).

Normally, the Academy would concurrently release a comprehensive Special Procedures Briefing for appropriate training along with a scheduled new protocol release. However, due to the urgency to get a working protocol out to the thousands of PSAPs and communication centers now, in the interim we advise the following:

    1. Each Emergency Dispatcher must read this entire document. They must also read the Protocol in its entirety at least twice - and once out loud to a dispatch partner. This should be required by an official internal staff memorandum implementation policy issued by each agency.
    2. This Protocol is not specific to any vehicle make or model, as various forms of accelerator problems have occurred sporadically over many years and in many makes and models. While the current public awareness is focused on Toyota models, this Protocol is built to handle such occurrences in both automatic and manual/stick transmission vehicles and vehicles with different ignition types such as standard key vs. on/off button. However, it is important to understand that this Protocol may not exactly cover all vehicle types, ignition types, and automatic vs. shift-stick types; nor will it cover all driving situations that might possibly present themselves.
    3. This Protocol is constructed in Panel/Logic/Sequence format which is the same scripted methodology used in Pre-Arrival Instructions of the Advanced MPDS, FPDS, and PPDS, which builds upon previous familiarity of PAI use by IAED-certified EPDs, EFDs, and EMDs.
    4. The protocol basically has four objectives:
        1. Getting vehicle into Neutral or "N" - the preferred method
        2. Turning off the engine (but not the entire electrical system) - the back-up "last resort" method
        3. Slowing and stopping the vehicle
        4. Providing safety instructions
    5. Safety instructions revolve around managing the situation at the end resting place of the vehicle including the occupants involved. The vehicle could stop on the roadway, partially off the roadway, all the way off the roadway, in a freeway divider/traffic island/median strip, in an inherently unstable location, etc. While the Protocol does not advise exiting the vehicle, this may be something that the occupants state they are going to do. These instructions attempt to make them as safe as possible as they do so.
    6. Some special advice for the ED is listed in the Critical ED Information area at the end of the Protocol instructions. This is to remind the ED of some special circumstances and their implications in applying this Protocol. Especially important is the understanding and relaying the difference between turning the ignition to the ACC (accessory) position (good) vs. all the way off and/or removing the key (bad).
    7. Please report any cases received by your center, whether the Protocol was used or not, to the Academy at: Real-time cases aid the Academy greatly in evolving these protocols forward.
    8. The use and updating of this Protocol is governed by the Limited Use License below, which must be read and accepted by all users and agencies prior to any use.

International Academies of Emergency Dispatch HiRISC Policy

The International Academies of Emergency Dispatch considers any situation necessitating the provision of these instructions to be an extremely High Risk-Inherent Situation Case (HiRISC), and believes that the trained Emergency Dispatcher (certified EMD, EFD, EPD) or their agency, making a good faith attempt to provide these instructions, should not be held responsible for any bad outcomes. This should not be considered a legal interpretation, but a strong official opinion of the Council of Standards and the Board of Trustees of the IAED.

How To Obtain and Update

For ProQA users:

To install the Accelerator Stuck Protocol, download the latest ProQA builds from the ProQA FTP site. The Accelerator Stuck Protocol is included in all three disciplines of ProQA. To download the latest builds, please go to the FTP request site and request access to the ProQA FTP site: 

For Cardset users and any other PSAP agreeing to the Limited Use License:

We have provided a .pdf of the Accelerator Stuck & Can't Stop Vehicle Protocol (North American English) () which can be used in pull out fashion. You can download and print to have at your workstations for the calltaker to use. Print as two cards, fold together as a two-sided protocol. There is a pullout tab on one side that can be self-laminated using clear tape and cut to fit.
