This guide covers common installation, configuration and traffic-behaviour problems with Cryptic Emergency Traffic v4.0.0.

Before testing, confirm that the current DLL and its supplied configuration are installed correctly. Make one change at a time so you can identify what affects the result.

Plugin Does Not Load

Check that:

  1. You are using Grand Theft Auto V Legacy.
  2. RagePluginHook launches the game successfully.
  3. LSPDFR loads and you can go on duty.
  4. CrypticEmergencyTraffic.dll is installed in plugins\LSPDFR.
  5. CrypticEmergencyTraffic.ini is alongside the DLL.
  6. No older DLL copies remain elsewhere in the plugins directory.
  7. Your RagePluginHook log contains no relevant loading errors.

The expected location is:

Grand Theft Auto V Legacy\plugins\LSPDFR\

Keep only one installed copy of CrypticEmergencyTraffic.dll. Duplicate copies can cause the wrong version to load or allow the plugin to load more than once.

Traffic Does Not React

First check whether your emergency vehicle meets the activation conditions described in the supplied configuration.

Then check whether the civilian vehicle is relevant. Traffic may intentionally remain unaffected when it is:

  • Travelling in the opposite direction
  • On an opposite carriageway
  • Behind your emergency vehicle
  • On an unrelated or crossing road
  • Outside the relevant detection area
  • Not meeting the configured relevance conditions
  • Involved in an LSPDFR pursuit or traffic stop
  • An emergency vehicle or protected backup unit

To test:

  1. Confirm that the plugin loaded successfully.
  2. Use a supported emergency vehicle.
  3. Meet the configured activation conditions.
  4. Find civilian traffic ahead of you travelling in the same direction.
  5. Test on a straightforward section of road.
  6. Check whether another plugin is controlling the same vehicles.
A vehicle remaining unaffected does not necessarily indicate a fault. The system deliberately filters out traffic that does not need to respond.

Traffic Reacts Too Much

If unrelated vehicles appear to react:

  1. Back up your configuration.
  2. Test with the INI supplied with v4.0.0.
  3. Check the affected vehicles’ direction and carriageway.
  4. Temporarily disable other traffic-yielding plugins.
  5. Repeat the test under similar conditions.

Pay particular attention to divided roads, junctions and roads running alongside one another.

Larger detection values do not automatically improve results. Depending on the setting, an adjustment may widen eligibility or make filtering less restrictive.

Erratic Steering or Stop-Start Movement

Unexpected behaviour may include sudden braking, repeated stopping, excessive lane changes or unusual steering.

Test with:

  • The supplied configuration
  • A single installed Cryptic Emergency Traffic DLL
  • Other traffic-yielding plugins temporarily disabled
  • A road with enough space for civilian vehicles to manoeuvre

Cryptic Emergency Traffic uses GTA V’s native driving AI for steering and lane positioning. Road layout, congestion and competing vehicle tasks can affect the result.

Avoid running multiple emergency traffic-yielding plugins simultaneously unless compatibility has been confirmed. They may assign conflicting instructions to the same vehicle.

Excessive Braking

If civilian traffic brakes more sharply than expected:

  1. Confirm that v4.0.0 is the installed version.
  2. Restore the supplied configuration after backing up your edits.
  3. Temporarily disable other traffic-management plugins.
  4. Compare behaviour at different approach speeds.
  5. Check whether congestion or an obstacle is limiting the vehicle’s movement.

The yielding system does not use SET_VEHICLE_FORWARD_SPEED to directly force a vehicle’s forward speed.

Native driving AI can still brake sharply in response to traffic, obstacles or assigned driving behaviour. The absence of forced forward speed does not eliminate every instance of sudden braking.

Opposite-Direction Traffic Reacts

Opposite-direction and opposite-carriageway traffic are intended to be excluded from normal yielding behaviour.

If these vehicles consistently react:

  1. Confirm that you are using the current DLL and supplied INI.
  2. Test on a straight road where vehicle headings are clear.
  3. Repeat the test on a divided road.
  4. Temporarily disable other traffic-yielding plugins.
  5. Record the location, vehicle directions and conditions.
  6. Check the affected session’s log for errors.
A short video can help distinguish opposite-direction traffic from vehicles turning, merging or changing heading at a junction.

If the issue remains reproducible with the supplied configuration and other traffic-yielding plugins disabled, report it as a potential filtering bug.

Problems During Pursuits

Pursuit suspects, backup units and other emergency vehicles are protected from ordinary civilian yielding behaviour.

If an involved vehicle behaves unexpectedly:

  1. Confirm that the pursuit is managed by LSPDFR.
  2. Identify whether the affected vehicle is a suspect, backup unit or unrelated civilian.
  3. Test with the supplied configuration.
  4. Check other pursuit, backup and traffic-management plugins.
  5. Review the logs around the time of the issue.
Pursuit protection does not mean all surrounding civilian traffic is ignored. Relevant civilian traffic may still react while involved pursuit vehicles remain protected.

Problems During Traffic Stops

Vehicles involved in LSPDFR traffic stops are protected from normal civilian yielding.

If a stopped vehicle unexpectedly moves or changes behaviour:

  1. Note whether the stop was active when the movement began.
  2. Record which plugin or interaction initiated the stop.
  3. Check other plugins that modify traffic stops or civilian tasks.
  4. Test with the supplied configuration.
  5. Review the affected session’s logs.
Unexpected movement alone does not establish which plugin caused it. Include the sequence of actions before the movement when reporting the issue.

Configuration Changes Have No Effect

Check that:

  • The file is named CrypticEmergencyTraffic.ini.
  • It has not been saved as CrypticEmergencyTraffic.ini.txt.
  • It is alongside the installed DLL in plugins\LSPDFR.
  • You are editing the configuration for the installed release.
  • Setting names and section headings remain unchanged.
  • Values follow the formats and limits described in the comments.
  • You saved the file while GTA V and RagePluginHook were closed.
  • You restarted the game before testing.
Do not overwrite the current configuration with an older INI. Transfer supported preferences into the newly supplied file.

Cryptic Emergency Traffic does not automatically generate, modify or overwrite the configuration.

Restarting the plugin will not add missing options to an older INI. Obtain the configuration supplied with your installed release.

Checking Logs

Review the RagePluginHook log and any relevant LSPDFR logs from the affected session.

Look for:

  • Cryptic Emergency Traffic loading messages
  • Loading failures
  • Missing dependencies
  • Exceptions mentioning the plugin
  • Errors occurring at the time of the unexpected behaviour

Read the surrounding entries rather than only the final error message.

Copy the affected session’s log before launching the game again. Include the complete log when requesting support so its context can be reviewed.

Reporting an Issue

Include:

  • Your Cryptic Emergency Traffic version
  • Your GTA V Legacy version
  • Your LSPDFR version
  • Your RagePluginHook version
  • A description of the expected and actual behaviour
  • The emergency vehicle used, including whether it is an add-on
  • The active emergency equipment and relevant activation settings
  • The location and road type
  • The affected vehicle’s direction and position relative to you
  • Whether a pursuit or traffic stop was active
  • Whether the issue happens consistently or occasionally
  • Steps to reproduce it
  • Your CrypticEmergencyTraffic.ini
  • The RagePluginHook log from the affected session
  • Other traffic, pursuit or backup plugins involved
  • The troubleshooting steps already completed
Include screenshots or a short video where possible. Road layout, vehicle positions and the timing of a reaction are particularly useful when investigating traffic behaviour.
