Señales de tránsito que todo camionero debe conocer

A complete stop is required at the stop line, before the crosswalk, or before entering the intersection. Stop fully, yield as required, and proceed only when safe.

Give the right-of-way to traffic or pedestrians already in or approaching the conflict area. Slow down, be ready to stop, and enter only when there is a safe gap.

A plaque below STOP means every approach is stop-controlled. Stop, identify arrival order, and yield to traffic with priority.

The maximum legal speed under normal conditions; the displayed number is in miles per hour. Do not exceed the number and reduce speed further for weather, traffic, curves, or work zones.

Traffic must not travel below the posted minimum unless conditions require it. Maintain at least the posted speed when safe; use another route if the vehicle cannot.

A stated rule applies except where another sign gives a different instruction. Watch for the next controlling sign and follow the more specific posted rule.

Right turns are prohibited at the location or during the times shown. Continue straight or use a permitted route; do not begin the turn.

Left turns are prohibited at the location or during the times shown. Continue straight or follow an alternate legal route.

Reversing direction with a U-turn is prohibited. Continue and use a legal turnaround location.

Traffic in the identified lane must move in the direction shown. Complete the required movement or change lanes safely before reaching the solid lane line.

The named lane is reserved for the displayed movement. Turn as directed or move to an appropriate lane early and safely.

Arrows show which movements each approach lane permits. Select the correct lane before the intersection and follow its arrow.

Passing another vehicle is prohibited through the signed section. Remain in lane and wait until passing is legally permitted.

The no-passing restriction has ended, but passing is allowed only when safe and legal. Check sight distance, traffic, pavement markings, and the truck's acceleration space.

Slower vehicles should use the right lane except when passing or preparing for a permitted movement. Move right when safe and avoid blocking faster traffic.

Trucks must use the right lane in the signed section. Move into the right lane safely before the restriction begins.

Traffic must pass to the right of an island, obstruction, or median. Position the vehicle to the right early; check trailer off-tracking and clearance.

Entry from this direction is prohibited, commonly at a one-way road or ramp. Do not enter; stop safely and choose a legal route.

The vehicle is traveling or about to travel against the legal direction of traffic. Stop safely, avoid continuing, and correct direction only when it can be done legally and safely.

Truck traffic is prohibited beyond the sign unless an exception is posted. Do not enter; follow the approved truck route.

Trucks may not use the road as a through route; local access may depend on posted law. Use the designated truck route and confirm whether a local-delivery exception applies.

Motor vehicles are prohibited from entering the facility or road. Do not enter with the CMV.

Traffic travels only in the arrow's direction. Enter and travel only in the direction shown.

A central divider separates opposing traffic; the arrow shows the permitted side. Keep on the correct side of the divider and do not turn into opposing lanes.

Parking is prohibited under the conditions or times shown; stopping briefly may still be regulated separately. Read arrows, times, vehicle exceptions, and curb rules before stopping.

Vehicles must not stop within the railroad crossing. Do not enter unless there is enough space to clear every track completely.

The arrow identifies the required stopping point for a red signal. Stop at the marked line or location, not inside the intersection or crosswalk.

The indicated turn is prohibited while the signal is red. Wait for a permitted signal indication before turning.

A green circular signal permits the left turn only after yielding to conflicting traffic and pedestrians. Wait for a safe gap; do not treat the green circle as a protected arrow.

The roadway is closed to traffic beyond the barricade or sign. Do not proceed; follow the posted detour.

The road is closed farther ahead; only traffic with a local destination should enter. Through traffic must detour now; confirm local access before entering.

Vehicles above the displayed gross or class-specific weight are prohibited. Know the vehicle's actual weight and take an approved alternate route if over the limit.

The maximum weight allowed on one axle or axle group is posted. Check axle weights, not only gross weight; reroute or adjust the load legally.

Different maximum weights apply to different vehicle combinations. Match the CMV configuration to the correct symbol and limit.

A weight restriction begins at the distance or turn shown. Choose the alternate truck route before reaching the restricted structure.

The arrow identifies a designated route for truck traffic. Follow the arrow and remain on the approved truck route.

The route is designated for vehicles carrying regulated hazardous materials. Follow the designated route and all permit or routing requirements.

Specified hazardous-material vehicles may not use the route. Do not enter with the covered load; follow the authorized HM route.
