Trinidad & Tobago Driving Rules for Americans (2026)
Drive on the LEFT. At roundabouts, yield to traffic already in the circle (which approaches from your right). Speed limit is 50 km/h urban, 80 km/h main roads, 100 km/h on the Solomon Hochoy Highway. BAC limit is 0.08%.

Rule #1: You Drive on the Left
Trinidad & Tobago is a former British colony and still drives on the left side of the road. The steering wheel is on the right, gear shift on your left hand, and you overtake on the right.
This is the single biggest adjustment for American drivers. Most accidents involving US tourists in Trinidad & Tobago happen at one of these moments:
- Pulling out of a hotel parking lot or driveway — instinct sends you to the right lane.
- Exiting a roundabout — you may drift toward the wrong side.
- Reversing — your spatial reference is reversed.
- Turning at a quiet intersection — easy to forget which lane to enter.
Mental cue: The driver should always be near the centerline of the road. If you can suddenly see more curb on your driver's side than passenger side, you've drifted to the wrong lane — correct immediately.
Speed Limits (in km/h)
All speed limits in Trinidad & Tobago are posted in kilometers per hour. Your rental car's speedometer will be in km/h. Here are the defaults when no sign is posted:
| Road Type | Limit (km/h) | US Equivalent (mph) |
|---|---|---|
| Urban / built-up area | 50 km/h | ~31 mph |
| Rural / open road | 80 km/h | ~50 mph |
| Solomon Hochoy Highway | 100 km/h | ~62 mph |
| School zones | 30 km/h | ~19 mph |
| Tobago mountain roads | 40–60 km/h | ~25–37 mph |
Speeding fines run $500–$2,000 TTD ($73–$294 USD). The TTPS uses both stationary and mobile radar units, especially along the Solomon Hochoy Highway and through Chaguanas.
Roundabouts — Yield to Traffic from Your Right
Roundabouts are common in Trinidad & Tobago and are the most consistently confusing element for Americans. The rule is simple but the geometry is reversed from what you're used to:
- Traffic in the roundabout has the right of way.
- You enter going left (clockwise from above).
- Yield to traffic coming from your right — that's the side where cars already in the circle approach from.
- Signal left before your exit (this is critical and locals expect it).
- Don't stop in the roundabout unless forced to — keep flowing.
Major roundabouts you'll encounter: Grand Bazaar (Valpark), Trincity, Macoya, Aranguez, and the various roundabouts along the East-West Corridor.
Mental model swap: In the US you scan left first at a 4-way stop. In Trinidad & Tobago, you scan right first at every roundabout and most intersections.
No "Turn on Red" Concept
In the US, you can turn right on a red light after stopping. That concept does not exist in Trinidad & Tobago, and even mentally, since you drive on the left, the equivalent move would be turning left on red — which is also not allowed.
A red light is a hard stop. Wait for green. The TTPS will ticket on the spot, and there are increasing numbers of red-light cameras around Port of Spain.
Seat Belts, Child Seats & Phones
- Seat belts: Mandatory for the driver and front passenger. Strongly recommended for rear passengers, and required if seat belts are fitted in the rear. Fine: $1,000 TTD (~$147 USD).
- Child seats: Children under 5 must use an appropriate child restraint. Rental agencies rent seats for ~$30–$50 TTD/day.
- Handheld phone use: Illegal while driving. Fine: $1,000 TTD (~$147 USD). Bluetooth and speakerphone with the phone in a cradle is permitted.
- Texting: Same penalty bracket as phone use; cumulative offenses can mean court appearance.
Alcohol & Drugs
The legal BAC limit in Trinidad & Tobago is 0.08% — the same as most US states. But enforcement is much stricter, especially around Carnival, when TTPS sets up frequent roadside breath-test checkpoints.
- First-offense DUI fine: $4,000+ TTD (~$590+ USD), license suspension, possible jail time.
- Refusing a breath test: Treated as guilty. Mandatory court appearance.
- Drugs: Trinidad & Tobago has decriminalized small amounts of marijuana for personal use, but driving under the influence remains illegal and is enforced via field sobriety tests.
- Best practice for tourists: Zero alcohol if driving. Use a taxi or designated driver, especially during Carnival fetes.
Road Signs You'll See
Signage in Trinidad & Tobago largely follows the British / Caribbean standard, with red circles for prohibitions, red triangles for warnings, and blue circles for mandatory actions. Signs are in English.
- STOP: Red octagon with white "STOP" — same as US.
- Give Way: Inverted red triangle. Equivalent to a US yield sign.
- Speed limit: Red circle with number (km/h). No "MPH" anywhere.
- No Entry: Red circle with white horizontal bar. Common on one-way streets in Port of Spain.
- Roundabout ahead: Triangle with three curved arrows.
- School zone: Triangle with children silhouette.
Road Conditions — What to Expect
- Trinidad main highways: Generally good. The Solomon Hochoy Highway, Churchill Roosevelt Highway, and Uriah Butler Highway are well-paved multi-lane roads.
- Trinidad secondary roads: Mixed. Potholes are common, locally called "pot-hong" or just "potholes" — drivers swerve around them, sometimes into oncoming lanes.
- Tobago roads: Narrower, often single-lane in each direction, with sharp bends through hills. The Northside Road in Tobago has stunning views but demands focus.
- North Coast Road (Trinidad): The drive to Maracas Beach winds through the Northern Range — beautiful, but lots of switchbacks and limited shoulder.
- Rainy season (June–December): Sudden heavy downpours flood low-lying roads, particularly in Caroni and parts of central Trinidad.
