When two lanes merge, drivers from each lane should alternate in turn. This reduces congestion and improves fairness in traffic.

Use the left lane only when needed. Staying there unnecessarily disrupts traffic and violates road discipline.

Crossing solid lines is not allowed unless unavoidable. They are used in high-risk or visibility-sensitive areas.

Dashed lines allow lane changes but only when safe and with proper signaling.

These markings help drivers align correctly with traffic flow ahead, especially before lane reductions.

This minimizes disruption and ensures that faster vehicles can pass safely through confined tunnel space.

Lane arrows help inform drivers of which directions are permitted, avoiding confusion at junctions.

Blocking bus bays interferes with public transport efficiency and endangers safety for passengers.

Other drivers must avoid bus lanes unless signage permits use during specific times.

In fog, rain, or snow, remaining in your lane helps maintain safe distances and avoid confusion.

Merging drivers must wait for a safe gap. Those already in the lane have priority.

Lingering in the left lane causes delays and potential road rage incidents. Return once you pass.

Indicators notify others of your intent, allowing safer coordination and preventing side collisions.

These are usually seen at intersections, allowing full turning flexibility from that lane.

Legal crossing of solid lines is allowed only to avoid hazards or when directed by authorities.

This regulated merging pattern is especially effective near lane closures or construction.

Motor vehicles are not allowed to drive, stop, or park in these lanes. Violators may be fined.

Vehicles must stop before this line when a red light or stop sign is present.

Overhead signals are enforceable and indicate immediate lane changes for safety.

During construction or detours, new paint or cones must be obeyed as official direction.

This buffer reduces the risk of collision due to wind turbulence, sudden swerving, or errors in driver judgment. It helps ensure cyclists’ safety.

These dynamic signals indicate that the lane is currently active and safe to use. They help guide traffic flow on variable lane roads.

Road signs or pavement markings are provided well in advance of lane changes. This gives drivers ample time to adjust safely.

Yellow curb markings indicate strict no-stopping zones. These are often near intersections, hydrants, or areas needing free movement.

Staying in the right lane improves traffic flow when exiting early. It also reduces conflict with vehicles continuing through.

Turning from the correct lane prevents confusion and abrupt movements. It also reduces the risk of side-impact collisions.

When being overtaken, drivers must maintain lane and speed. Swerving or accelerating creates unnecessary danger.

A broken line permits overtaking where visibility and safety allow. Drivers must still use caution and proper signaling.

This zipper merge technique improves fairness and traffic efficiency. It minimizes last-second lane cutting and reduces delays.
