Interior Checkpoint Network
The U.S. Border Patrol operates approximately 224 interior checkpoints across the country:
- ~35 permanent checkpoints (fixed structures on major highways)
- ~189 tactical/temporary checkpoints (moveable, secondary roads)
This guide covers the permanent checkpoint locations in each major border state.
Texas
Texas hosts the most extensive checkpoint infrastructure, intercepting northbound traffic from the Rio Grande Valley and Laredo sectors.
Permanent Checkpoints
| Location | Highway | Notes |
|---|---|---|
| Falfurrias | US-281 | Largest volume, major commercial traffic |
| Laredo (North) | I-35 | North of Laredo |
| Sierra Blanca | I-10 | Between El Paso and Van Horn |
| Marfa | US-67 | West Texas |
| Sarita | US-77 | South of Kingsville |
| Javier Vega Jr. | US-77 | Named checkpoint |
Operational Notes
- Sierra Blanca recently installed the GRAB 350 active vehicle barrier — an autonomous tire-shredding system to stop vehicles attempting to evade
- Checkpoints are compounded by Operation Lone Star (state initiative)
- State troopers heavily patrol checkpoint approaches
- Texas SB 4 affects enforcement even before reaching federal checkpoints
State Law Interaction
Texas law requires local cooperation with federal immigration enforcement. Expect:
- State troopers may assist at checkpoints
- Roving patrols by both state and federal agents
- Enhanced enforcement throughout border region
California
California checkpoints create a secondary enforcement layer north of San Diego and the Imperial Valley.
Permanent Checkpoints
| Location | Highway | Notes |
|---|---|---|
| San Clemente | I-5 | Major checkpoint between San Diego and LA |
| Temecula | I-15 | Riverside County |
| Pine Valley | I-8 | East of San Diego |
| Highway 86 | CA-86 | Imperial Valley |
SB 54 Protections
California's sanctuary law (SB 54) provides protections, BUT:
- Federal checkpoints are NOT affected — CBP operates independently
- SB 54 limits what state and local officers can do
- CBP agents at federal checkpoints have full authority
Recent Developments
- Supreme Court orders have protected CBP's ability to run roving patrols in Southern California communities
- CBP relies heavily on checkpoints and roving patrols given state non-cooperation
Arizona
Arizona checkpoints surround the Tucson and Yuma operational sectors.
Permanent Checkpoints
| Location | Highway | Notes |
|---|---|---|
| Tubac (North) | I-19 | Between Nogales and Tucson |
| Gila Bend (Near) | SR-85 | West of Phoenix |
| Sierra Vista | SR-90 | Near Fort Huachuca |
| Tombstone | SR-80 | Cochise County |
Constitutional Issues
- Arizona ACLU has frequently litigated against CBP for:
- Exceeding "brief inquiry" scope
- Prolonged detention for asserting silence
- Physical force incidents
- Racial profiling
SB 1070 Legacy
While much of Arizona SB 1070 was struck down, aggressive enforcement culture persists in:
- Local sheriff cooperation
- Joint federal-state operations
- Enhanced roving patrols
New Mexico
New Mexico checkpoints focus on interstate traffic moving west toward Arizona or north toward Albuquerque.
Permanent Checkpoints
| Location | Highway | Notes |
|---|---|---|
| Las Cruces (West) | I-10 | Between Las Cruces and Arizona |
| Las Cruces (North) | I-25 | Mile marker 26, north of Las Cruces |
| Radium Springs | US-185 | Along Rio Grande |
Traffic Patterns
- I-10 checkpoint intercepts east-west traffic
- I-25 checkpoint intercepts north-south traffic toward Albuquerque
- Tactical checkpoints frequently set up on secondary roads
Florida
Florida presents a unique enforcement environment.
No Traditional Land-Border Checkpoints
Florida lacks land-border CBP checkpoints, BUT:
- Entire state is within the 100-mile coastal zone
- Heavy reliance on 287(g) agreements with local agencies
- SB 1718 creates parallel state enforcement
Agricultural Inspection Stations
Florida has begun utilizing agricultural interdiction stations on interstates as dual-purpose checkpoints:
- Commercial vehicle inspections
- Immigration status checks
- 287(g) officers present
- Heavy targeting of truck drivers
SB 1718 Impact
| Provision | Effect |
|---|---|
| Out-of-state undocumented licenses invalid | Criminal charge for driving |
| Transporting undocumented persons | Felony (human smuggling) |
| Hospital data collection | Tracking place of birth |
Roving Patrols vs. Checkpoints
Beyond fixed checkpoints, Border Patrol conducts roving patrols throughout the 100-mile zone.
Key Differences
| Feature | Checkpoint | Roving Patrol |
|---|---|---|
| Suspicion required | None | Reasonable suspicion |
| Location | Fixed | Mobile |
| Legal standard | Martinez-Fuerte | Brignoni-Ponce |
| Can stop any vehicle | Yes | Only with articulable facts |
Common Roving Patrol Areas
- Secondary roads near checkpoints (evading traffic)
- Border communities
- Agricultural areas
- Commercial vehicle routes
Checkpoint Avoidance
Legal Considerations
- Taking alternative routes to avoid checkpoints is legal
- However, roving patrols often monitor those routes
- Avoiding behavior may contribute to "reasonable suspicion"
Practical Reality
- Permanent checkpoints are difficult to avoid on major highways
- Alternative routes often have tactical checkpoints
- GPS apps sometimes show checkpoint locations
Your Rights Apply Everywhere
Regardless of which checkpoint you encounter:
- Right to remain silent (Fifth Amendment)
- Right to refuse search (Fourth Amendment)
- Right to record (First Amendment)
- Right to attorney if detained
Universal Script
At any checkpoint:
"Am I free to go, or am I being detained?"
If asked to search:
"I do not consent to a search of my vehicle or belongings."
If detained:
"I wish to remain silent. I want to speak to an attorney."
