Serving South San Diego County Employers
National City and Chula Vista are home to a significant concentration of San Diego County's industrial, warehouse, logistics, and construction employers. From the National City industrial corridor along Bay Marina Drive to Chula Vista's Otay Ranch commercial districts and manufacturing operations near the border, these are businesses that depend on reliable, fast drug testing.
On Point Drug Testing serves both cities as a core part of our San Diego County coverage area. We are typically able to reach most National City and Chula Vista locations within 1–2 hours of your call.

DOT Testing for Border-Adjacent Trucking
The Otay Mesa Port of Entry is one of the busiest commercial border crossings in the United States. Trucking companies and freight operations in this area often have significant FMCSA compliance obligations. On Point Drug Testing performs DOT urine specimen collections following all 49 CFR Part 40 requirements for carriers operating in this corridor.
Post-accident testing in this area is especially critical given the complexity of cross-border operations. Call us immediately after any qualifying accident — 619-241-4415 — and we'll mobilize as fast as possible.
Understanding Your Compliance Obligations in South Bay
Employers in National City and Chula Vista span a wide range of industries — auto dealerships along the Mile of Cars, distribution centers near Otay Mesa Road, healthcare clinics, staffing agencies, and small manufacturers. Each sector has different testing obligations. DOT-regulated employers (trucking companies, bus operators, pipeline workers) must follow 49 CFR Part 40 to the letter. Non-DOT employers are largely governed by their own written policies, California law, and any contractual requirements from their clients or insurers.
California AB 2188, effective January 1, 2024, limits how employers can act on positive cannabis results for off-duty use — but it does not ban pre-employment or reasonable suspicion testing for most roles. DOT-regulated employees remain subject to federal rules that supersede California law entirely. If you're unsure what applies to your operation, call 619-241-4415 and we can walk you through it.
Post-Accident Testing in High-Traffic Industrial Areas
The stretch of National City and Chula Vista between the 5, 805, and 54 freeways is one of the highest-traffic commercial corridors in San Diego County. Delivery drivers, forklift operators, and warehouse workers operate under significant physical and time pressure. When an incident occurs — a forklift collision, a loading dock injury, a vehicle accident during a delivery run — the window for post-accident testing is short.
DOT post-accident testing for CDL drivers must happen within 8 hours for alcohol and 32 hours for drugs. Non-DOT employers have no federally mandated window, but the practical standard is to test as soon as it is safe to do so — ideally within a few hours. On Point is available 7 days a week, 7AM–7PM, and can reach any location in National City or Chula Vista within the response window. Call 619-241-4415 immediately after securing the scene and getting medical attention for anyone injured.
Setting Up an Ongoing Program for South Bay Employers
Many South Bay employers start with pre-employment testing and expand from there. A basic program includes pre-employment screening, post-accident testing, and reasonable suspicion testing. Adding random testing — even at a modest rate of 10–25% annually for non-safety-sensitive roles — significantly strengthens your program's deterrent effect and your legal defensibility if a workplace incident ever results in litigation.
On Point offers program setup at no charge. We help you document your policy, establish a chain of custody process, and set up a roster for random testing. There are no contracts and no minimums — you pay per test. For South Bay employers running 10 or more tests per year, ask about fleet pricing when you call.
