Driving in Lanes

Proper driving in a lane is the foundation of safe driving. Sections 11 and 12 of Act 361/2000 Coll. specify where on the roadway you should drive, when you can change lanes, and how to behave on multi-lane roads.

Most drivers typically drive in the right lane. The left lane is designated for overtaking, turning left, or when the right lane is occupied.

Explanation

Basic Rule: Drive on the Right (Section 11)

Drive as far to the right as possible. This applies to:

• On a two-lane road: you drive in the right lane.
• On a road with three or more lanes in one direction: you drive as far to the right as possible.
• On a road without marked lanes: you drive at the right edge.

You only use the left lane when you have a reason:

• You are overtaking.
• You are turning left.
• You are bypassing an obstacle.
• In a municipality, you can also drive in the left lane if you do not slow down vehicles behind you that cannot otherwise overtake you.

Important: After overtaking, always return to the right lane. Long driving in the left lane without reason is an offense.

Lane Change (Section 12)

When changing lanes, the following applies:

1. A driver changing lanes must not ENDANGER or RESTRICT the driver in the lane they are merging into. 2. Before changing lanes, you must:

• Turn on your turn signal
• Check the rearview mirror
• Check the blind spot
• Verify that there is enough space

3. On a multi-lane road in heavy traffic, the so-called lane driving applies:

• Drivers drive in all lanes side by side.
• When merging lanes (for example, when one lane ends), vehicles alternate one by one: zipper system.

Fine for changing lanes without signaling: 1,500 - 2,500 CZK, 2 points.

Example

Example - Three-Lane Highway:

You are driving in the right lane of the highway (maximum 130 km/h). A truck is driving in front of you at 80 km/h.

1. You look in the rearview mirror - the left lane is free. 2. You check over your left shoulder (blind spot) - no one is there. 3. Turn on your left turn signal. 4. Smoothly move into the left (middle) lane. 5. Overtake the truck. 6. Turn on your right turn signal. 7. Check the right side. 8. Return to the right lane.

MOST COMMON MISTAKE: The driver does not return to the right lane after overtaking and stays in the left lane. This is wrong and punishable!

Common mistakes

Typical Mistakes:

1. "I must drive in the right lane even in the city - NO, in the city you can use any lane, including the left, as long as you do not slow down the drivers behind you."

2. "I don't have to turn on my turn signal when changing lanes" - YOU MUST! Always signal a lane change.

3. "The zipper system is just a recommendation" - NO. It is a legally mandated obligation (Section 12, paragraph 4).

4. "I don't have to check the blind spot if I have mirrors" - YOU MUST! Mirrors do not cover the entire area beside the vehicle.

Explanation

Road Traffic Rules Drive -lanes, overtaking I. Rules for Driving in Lanes and for overtaking 1. Lane Use and Parallel Driving Outside municipality: • Drivers must normally use the right-hand lane. • Other lanes are used only for overtaking, turning, driving around an obstacle, or turning around. Inside municipality: • Drivers of motor vehicles may use any lane (parallel driving). • If vehicles in all lanes block a faster vehicle from behind, the driver in the leftmost lane must move aside as soon as possible. Vehicles over 3,500 kg, longer than 7 m, special vehicles (tractors) and vehicles with max speed 45 Km/h: • In municipality, they may use the left lane only when needed for: ◦ overtaking, ◦ driving around obstacles, ◦ turning, ◦ turning around. • On roads with three or more lanes in one direction, such vehicles may use only the two lanes closest to the right edge of the road. Zipper Merge • When changing lanes, a driver must not endanger or restrict drivers in the lane they are entering. • When a lane ends, drivers in the through lane must allow vehicles from the ending lane to merge alternately, one by one. 2. Overtaking I. Basic rules and direction of overtaking • Overtaking is normally done on the left. • Overtaking on the right is allowed only in two specific cases: You may overtake on the right if the vehicle ahead is clearly turning left. If you are driving in an joining (slip lane, onramp) or exit lane, you may overtake a vehicle driving in the through-lane. Overtaking is not: • situations of parallel driving vehicles inside municipality, when vehicle in one lane is travelling at a different speed than other vehicles in the same direction • situations of parallel driving, when a tram, bus or a vehicle using a reserved lane is travelling at a different speed than other vehicles moving in the same direction II. General prohibitions on overtaking A driver must not overtake when: • Safe re-entry is not guaranteed - If you cannot safely return to your lane in front of the overtaken vehicle(s). • You would endanger or restrict oncoming traffic - You must not force an oncoming driver to brake or evade. • At a pedestrian crossing , cycle crossing and railroad crossing (and immediately before them) - Strictly prohibited. • Vehicle ahead signals a left turn - If the vehicle in front indicates left and you cannot overtake on the right (according to section I.2), overtaking is forbidden.

• Vehicle turning left
• In an joining or exit lane

How to remember it

Practical Summary:

Driving in Lanes – What to Do and Not Do:

• Outside of a municipality: ALWAYS drive in the right lane. The left is only for overtaking.
• In a municipality: You can drive in any lane (but you must not unnecessarily slow down other drivers).
• Before changing lanes: turn signal → side mirror → blind spot (turning your head) → merge.
• After overtaking, ALWAYS return to the right lane.

Most common offense: Driving in the left lane without reason outside of a municipality – it restricts other drivers and you may receive a fine.

Practical tip on the highway: If someone is overtaking you on the right, you are in the wrong lane. Move to the right.

Check what you remember

Five questions from the official bank. The answer appears only after you choose — try to recall it first, that is what makes learning stick.

1. Question 1 of 5

   Outside built-up areas, on a road with two or more lanes in one direction of travel, vehicles travel:

   
   In the left-hand lane. Other lanes may be used if it is necessary for overtaking, passing, turning around or turning off.In the right-hand lane. Other lanes may be used if it is necessary for overtaking, passing, turning around or turning off.In any lane, provided that the smooth flow of road traffic, particularly the passage of other vehicles, is not impeded.

   § 12

2. Question 2 of 5

   A driver may only change from one lane to another if:

   They do not impede a driver travelling in the lane they are entering; they do not give a direction signal.They do not endanger a driver travelling in the lane they are entering; they do not give a direction signal.They do not endanger or impede a driver travelling in the lane they are entering; they must give a direction signal.

   § 12
