Cryptic Emergency Traffic 3.0.0

(2 reviews)

1 Screenshot

Let's be honest.

You turn on your lights and siren because you need to get somewhere.

Then the car ahead starts brake-checking you. The pursuit suspect suddenly decides to yield. Your backup gets stuck behind traffic, and your emergency response becomes a battle with GTA's driving AI.

That's why I rebuilt Cryptic Emergency Traffic from scratch.

This rebuild focuses on reducing interference with LSPDFR while letting GTA's driving AI handle steering and lane positioning. It doesn't repeatedly replace civilian driving tasks or force cars towards scripted pull-over coordinates.

What It Does

  • Separate Code 2 and Code 3 settings for lights-only and lights-and-siren responses.

  • Uses GTA's emergency yielding behaviour during normal responses, with configurable minimum activation speeds.

  • Disables the plugin's broad yielding requests during active pursuits to avoid encouraging suspects and pursuing units to pull over.

  • Offers an optional pursuit response that gently limits the speed of eligible civilian vehicles ahead of you, travelling in the same direction.

  • Excludes known LSPDFR suspect vehicles, emergency vehicles, player vehicles and persistent vehicles from those civilian speed adjustments.

  • Suspends the plugin's yielding requests during active traffic stops and when you're stationary or moving below the configured response speed.

  • Restores speed limits applied by the plugin when vehicles are no longer relevant.

  • Supports additional emergency vehicle model names through the configuration.

  • Includes optional debug logging to help investigate problems.

  • Automatically creates CrypticEmergencyTraffic.ini on first load.

  • No additional keybinds.

Built Around LSPDFR

Pursuits already have enough going on without a traffic plugin repeatedly telling the suspect to do something else.

The rebuild checks LSPDFR's pursuit and traffic-stop state before applying its traffic logic. During pursuits, the optional civilian response focuses on eligible traffic ahead of you and excludes vehicles identified by LSPDFR as suspects.

It also avoids assigning or clearing NPC driving tasks, reducing one source of interference with other plugins.

The aim is cleaner emergency responses with less disruption to the situations LSPDFR is already managing.

What to Expect

During normal responses, GTA's own driving AI controls how traffic yields. Road layout, congestion, vehicle behaviour and other installed mods can all affect the result.

During pursuits, the optional civilian response adjusts eligible vehicles' maximum speed. It doesn't force them to change lanes or guarantee a clear route.

At traffic stops, the plugin suspends its yielding requests. It doesn't currently add scripted routing to make vehicles drive around your parked cruiser.

I'm aiming for more consistent behaviour, but I'm not going to promise that every GTA driver suddenly becomes sensible.

Configuration

The plugin generates its configuration here:

Grand Theft Auto V Legacy\plugins\LSPDFR\CrypticEmergencyTraffic.ini

You can configure:

  • Code 2 and Code 3 response activation.

  • Minimum response speeds.

  • Pursuit civilian detection distances and speed percentages.

  • Whether the optional pursuit civilian response is enabled.

  • Additional emergency vehicle model names.

  • Scan interval and debug logging.

Additional vehicle models still need suitable emergency vehicle setup. Adding a model name to the configuration doesn't give it working emergency equipment or yielding behaviour by itself.

Updating from an Older Version

Remove the previous Cryptic Emergency Traffic installation before installing this rebuild, including any old copy of its DLL or PDB directly inside plugins.

Install the new DLL in:

Grand Theft Auto V Legacy\plugins\LSPDFR

The .ini is generated automatically when the plugin loads. Recognised older configurations are backed up before the new defaults are created.

What's New in Version 3.0.0

Released

v3.0.0

Complete Rewrite

  • Completely rewrote Cryptic Emergency Traffic from the ground up with a new modular architecture focused on natural behaviour, reliability and LSPDFR compatibility.

  • Replaced the previous aggressive task-forcing system with a cleaner traffic management system.

Added

  • Added speed and urgency-based traffic detection.

  • Added smarter vehicle relevance checks based on direction, position and proximity.

  • Added dedicated protection for LSPDFR pursuit suspects.

  • Added dedicated protection for vehicles involved in LSPDFR traffic stops.

  • Added improved emergency vehicle classification, including supported add-on emergency vehicles.

  • Added relative-speed yielding, allowing traffic to slow proportionally to its current speed.

  • Added configurable same-direction detection.

  • Added a safety threshold preventing clearly opposite-direction traffic from being treated as relevant.

  • Added a new fully commented .ini configuration that is never automatically generated or overwritten.

Changed

  • Yielding now uses GTA V's own driving AI to handle lane positioning and steering.

  • Significantly reduced forced and scripted vehicle manoeuvres.

  • Same-direction filtering is now performed before other traffic logic.

  • Opposite-direction and opposite-carriageway traffic is ignored.

  • Traffic is only retasked when its state actually changes, reducing unnecessary AI intervention.

  • Improved traffic detection performance and reduced unnecessary processing.

  • Improved emergency vehicle detection and exclusion.

Fixed

  • Fixed aggressive pull-over behaviour that could cause vehicles to flip or behave unnaturally.

  • Fixed opposite-direction traffic reacting on motorways and dual carriageways.

  • Fixed pursuit suspects being incorrectly treated as normal traffic.

  • Fixed vehicles involved in traffic stops being unnecessarily affected.

  • Fixed jerky and stop-start behaviour caused by repeated tasking.

  • Fixed unnatural braking caused by forcing vehicles to specific speeds.

  • Fixed vehicles remaining managed after they were no longer relevant.

  • Fixed unnecessary repeated task assignments.

Removed

  • Removed the previous aggressive task-forcing system.

  • Removed coordinate-based pull-over targets.

  • Removed forced low-speed behaviour.

  • Removed SET_VEHICLE_FORWARD_SPEED from the yielding system.

  • Removed runtime .ini generation and modification.

  • Removed the previous rigid state-machine approach.

Notes

Version 3.0.0 is a complete rewrite of Cryptic Emergency Traffic and replaces the previous traffic system.

The new system is designed around a simple principle: only affect the traffic that genuinely needs to react, and leave everything else alone.

It is recommended to remove previous versions and use the new fully commented CrypticEmergencyTraffic.ini included with this release.


Short Description

A simple, reliable AI traffic-yielding plugin designed to get traffic out of the way of emergency vehicles without the chaos.

AI disclosure

The author has disclosed that AI tools were used in creating the following aspects of this file:

  • Description
  • Images
  • Mod and Mod Content (Substantial)

I used Claude for earlier versions of Cryptic Emergency Traffic and ChatGPT to write the code for this rebuild, troubleshoot reported issues, and help prepare documentation and release materials. The release cover was also generated using AI. AI contributed substantially to this release; I remain responsible for reviewing, testing and maintaining the plugin.

Opposing traffic is no longer unnecessarily affected by the plugin.

Is this only on freeways or also on streets? Because realistically the reason opposing traffic IRL also moves to the side is so we can drive right down the middle if blocked in.

I normally don't write reviews, but your plugin helped so much! I can keep my lights on code 3 while I'm on a traffic stop and traffic goes around me, They don't back up the traffic, and make them act crazy!

I used to pull someone over and had to go from code 3 all the way back to code 2

so traffic would move around me on a traffic stop it made me so madmad!

I was doing 160 down the interstate and the ai traffic was moving perfect

Thank You! Thank You! Thank You!

Makes npc car act funky when you are in vehicle pursuit they stop and go like they are trying to pull over but they are running when you back off they drive fine but soon as you get close they start acting weird
