Roadside drug testing is the screening procedure police and gendarmerie units use at traffic checkpoints to determine whether a driver has used narcotic or stimulant substances. An oral fluid sample is taken from the driver, applied to a test kit and read by a police drug testing device that records the result.
This article covers how screening is carried out at the checkpoint, the functions expected from the devices used, how alcohol and drug enforcement are planned together, and what law enforcement agencies consider in procurement. For the operating logic of the device see our drug testing devices guide; for the alcohol side of the same checkpoint see police breathalyzers.
Why Roadside Drug Enforcement Is Carried Out
Driving under the influence of narcotic or stimulant substances is prohibited by traffic law in Türkiye, as in most jurisdictions, and law enforcement screens drivers with technical devices to establish whether such substances have been used. Where use is established, the law provides administrative fines, withdrawal of the driving licence and criminal provisions. The scope and duration of sanctions are set by legislation and should be verified against official sources.
Unlike alcohol enforcement, drug screening does not look for a quantity but for presence. This shapes the role of the device: a drug testing device does not measure a value, it reads the reaction of an oral fluid sample on the kit, produces a screening result and records it.
How a Roadside Drug Test Is Performed
At a checkpoint, drug screening generally follows this sequence:
- Stop and briefing: the driver is stopped and told what the procedure is and how it will be carried out. In most operations drug screening runs at the same point as alcohol testing, one after the other.
- Sample collection: oral fluid is collected from the driver with a collection pad. Because the sample is taken under observation, no private area or special arrangement is needed.
- Kit and device reading: the sample is applied to the test kit and the kit is inserted into the device. The device identifies the kit, manages the analysis itself and shows the result.
- Recording and report: the result is stored in the device with date and time. Driver and officer details are entered and a printout is attached to the official report.
- Next steps: the field result is a screening result. What follows a positive result is defined by legislation and the agency's procedures.
Because every step of the flow is managed by the device, no operator interpretation is required and different teams work to the same standard. At busy checkpoints that consistency matters as much as speed.
Functions Required in Roadside Drug Testing Devices
The enforcement environment sets different expectations from other applications. A device operating at the roadside, in a vehicle, in changing weather and across long shifts needs the following:
- Identity and officer entry: the driver's name and ID number and the details of the officer and unit can be entered into the device.
- Record memory: tests are stored with date and time and can be reviewed on screen later.
- Printed output: support for a wireless portable printer so the result is documented at the roadside.
- Refusal record: a driver's refusal to be tested can itself be recorded.
- Kit identification: the device recognises the kit automatically and will not start a test with an expired or previously used kit.
- Kit locking: analysis does not start until the kit is fully seated, securing the reading in vehicles and moving environments.
- Data transfer: records are transferred to a computer by software for archiving and reporting.
- Field durability and charging: a display readable in sunlight, a housing suited to harsh conditions, and charging in both vehicle and office environments.
All of these serve one purpose: a result obtained at the roadside must remain traceable and documentable after the checkpoint is over. See the UTC drug tester product page for device functions and the UTK drug test kit page for kit options.
Running Alcohol and Drug Enforcement Together
At traffic checkpoints alcohol and drug screening are usually carried out at the same point by the same team. An evidential breathalyzer is used for alcohol and an oral fluid based device for drugs; both are expected to record the result and produce a printout.
Operating two devices side by side raises procurement questions of its own: a common approach to data transfer and archiving, training of teams on both devices, joint planning of consumables and a single service contact. Because ARMAS manufactures both device groups in-house, these can be managed with one supplier. We describe the alcohol device class in police breathalyzers and its features in evidence class breathalyzer features and differences.
Procurement Considerations for Law Enforcement Agencies
When law enforcement bodies procure drug testing systems, device specifications alone are not a sufficient basis for the decision. The following are considered together:
- Writing the specification around functions and certification rather than brand names
- Securing kit supply for the service life of the device
- Agreeing a panel configuration that matches the agency's enforcement purpose
- Defining recording, reporting and central archiving requirements
- Setting storage and access rules for records in line with the agency's data protection policy
- Assigning responsibility for operator training, technical service and spare parts
- Interoperability with the existing breathalyzer fleet and a shared service arrangement
The general framework of institutional procurement is set out in our institutional breathalyzer procurement guide; the same principles apply to drug testing systems.
ARMAS Elektronik and Its Drug Testing System
ARMAS Elektronik designs and manufactures its drug testing device and test kit in Türkiye. Our drug testers range consists of the UTC drug tester used by enforcement teams, the single-use UTK drug test kit and the UTC-DATA software for managing records. On the alcohol side, our evidential breath alcohol testers are used at the same checkpoints.
You can review our references among public institutions, including police and gendarmerie, and contact us for a configuration and quotation suited to your agency.
Frequently Asked Questions
How is a roadside drug test performed?
An oral fluid sample is collected from the driver with a pad, applied to a test kit and the kit is inserted into the drug testing device. The device reads the result, records it with date and time and a printout can be produced. The result is a screening result.
Which sample does a roadside drug testing device use?
Oral fluid, that is saliva. Because the sample is collected under observation in a few steps, it suits roadside enforcement.
Does a roadside drug testing device give a definitive result?
No. Field devices screen; positive results are expected to be confirmed before any sanction. The device's role is to run the screening in a standardised way and to document the result.
Which functions are required in an enforcement device?
Identity and officer entry, time-stamped record memory, portable printer support, refusal recording, kit identification and locking, data transfer software, and a housing and charging options suited to field conditions.
Can breathalyzers and drug testing devices be procured together?
Yes. The two devices are used at the same checkpoint. Because ARMAS manufactures both product groups, training, service and consumables planning can be handled with a single supplier.
How is kit supply planned?
Annual test volume is estimated to determine kit requirements, and supply continuity is secured together with the device purchase. As the manufacturer we can plan this with your agency.
