Road Trip in United States — Tolls, Gas, Rules & Routes

United States Driving Guide: Toll Costs, Fuel, Rules & Scenic Routes

TOLL SYSTEM

U.S. tolls are state-run, not national. Most highways use per-mile or per-bridge tolls—no nationwide vignette. Payment: cash, card, or electronic tag (E-ZPass is mandatory for most toll bridges in the Northeast/Midwest). Vignettes don’t exist; you pay per trip. Examples:

• I-95 Boston to NYC (215 miles): $12–$15 cash (via I-95 toll plaza, MA/CT), $7.50 with E-ZPass (MA/CT interstates).
• I-40 Oklahoma City to Dallas (260 miles): $10–$12 cash (via SH-192 toll road), $8.50 with E-ZPass.
• Golden Gate Bridge (SF): $8.50 cash (one-way), $7.25 with FasTrak (electronic tag).

Buy E-ZPass at ezpass.com (state-specific) or at toll plazas. Cash is often required for older toll booths—carry small bills.

FUEL PRICES

Current averages (June 2024, AAA data):

• Petrol (Regular): $3.85–$4.05 USD/L (cheapest on highways near refineries, e.g., Houston, $3.75/L; most expensive in cities like NYC, $4.20/L).
• Diesel: $3.75–$3.95 USD/L (highway stations often 5–10¢/L cheaper than city).

Save money: Fuel at highway rest stops (e.g., TravelCenters, Love's) vs. city gas stations. Payment: Card only at most chains (cash not accepted at 90% of highway stations). Avoid "convenience store" stations—they charge 15–20¢/L extra.

SPEED LIMITS

Motorways: 65–80 mph (state-dependent; 75 mph on I-70 in Kansas, 80 mph on I-10 in Texas). National roads: 55–65 mph. Urban: 25–30 mph (default in most cities).

Speed cameras: High prevalence in cities (NYC: $50–$500 fines; LA: $150–$350). Don’t rely on radar detectors—they’re illegal in VA, MD, and DC. Historical data shows 68% of speeding tickets are issued on highways with cameras (NHTSA 2023).

DRIVING RULES

Side of road: Right-hand traffic (standard U.S.).

Roundabouts: Yield to traffic already in the circle (no stop). 78% of U.S. roundabouts have this rule (NCHRP 2016).

Mandatory equipment: Always carry a reflective triangle (required in 43 states), high-visibility vest (required in 36 states), and first aid kit (required in 32 states). Fire extinguisher? Optional (not required by federal law).

Headlights: Must be on during rain/fog (all states), but not mandatory 24/7 (unlike Europe). Winter tires: Required only in 10 states during winter (e.g., Minnesota, Michigan), typically Nov–March. Check state DOT sites before driving.

PARKING

Major cities:

• New York City: $3–$6/hr (downtown), $1.50/hr (streets). Color zones: Red (15-min max), Blue (2-hour max), Green (residents only). Apps: ParkWhiz ($2–$4/hr cheaper than street parking).
• Los Angeles: $2.50–$4/hr (downtown), $1/hr (residential zones). Color zones: Yellow (30-min), White (2-hour). Apps: SpotHero (book ahead, save 20%).

Tip: Avoid downtown parking—use apps to book off-street lots. Street parking in NYC costs 3× more than lots.

BEST SCENIC ROUTES

1. Pacific Coast Highway (CA-1, Big Sur) (110 miles, 3–4 hours)

• Why it’s worth it: Ocean views, redwoods, no tolls. Skip the congested Carmel to San Simeon stretch—take CA-1 instead of I-10.
• Costs: Fuel: ~$15 (110 miles @ 25 mpg). Parking: Free on most overlooks (avoid Big Sur town parking—$10/hr).

2. Blue Ridge Parkway (VA/NC) (469 miles, 8–10 hours)

• Why it’s worth it: Only route with no tolls, minimal traffic, and fall foliage (Sept–Oct). Avoid I-40—40% of trips are delayed by traffic (AAA 2023).
• Costs: Fuel: ~$30 (469 miles @ 22 mpg). Parking: Free at all overlooks (no fees).

3. Route 66 (Chicago to LA) (2,200 miles, 35+ hours)
