Driving on urban and interurban roads
As motorcyclists, our safety depends largely on our ability to anticipate and make ourselves visible. Due to the narrow profile of a motorcycle, other road users may not notice us or may misjudge our speed. In this topic, we break down the fundamental rules for riding safely and passing your theoretical exam.
1. Positioning and Anticipation on the Road
For safe riding, especially outside built-up areas, defensive driving is vital. We must assume we are vulnerable and anticipate possible mistakes by other drivers.
Positioning on the Roadway
- General rule: Motorcycles must ride on the right.
- Within the lane: We should occupy the central part of the lane, unless for safety reasons we need to move closer to the right (without leaving the lane) to facilitate passing or due to road conditions.
- Lane usage: If there is more than one lane in our direction, we will use the one furthest to the right. The others will be used for overtaking or when traffic conditions require it.
- Note: On roads with three lanes and two-way traffic, you must never ride in the center lane without a justified reason (overtaking or turning).
Safety Distances
Maintaining adequate space is our protective "shield."
| Situation Type | Distance Rule / Behavior |
|---|---|
| Riding behind another vehicle | Leave enough space to stop without colliding in case of sudden braking (minimum 2 seconds). |
| If not intending to overtake | Leave enough space so that others can overtake us safely. |
| Overtaking outside built-up areas | Minimum lateral separation of 1.5 meters. |
| Passing other vehicles (crossing) | Keep a prudent lateral safety distance. |
2. Speed
Proper speed is that which adapts to the circumstances (traffic, road, weather) without exceeding the limits.
When to moderate speed or stop?
It is mandatory to reduce speed, coming to a full stop if necessary, in the following situations:
- Presence of pedestrians or animals (especially children and the elderly).
- When approaching cycles (bicycles) on the road.
- At intersections, pedestrian crossings, and level crossings (railway crossings).
- When approaching stationary vehicles on the roadway.
- When the pavement is slippery, or there are clouds of dust or smoke.
- In cases of glare or reduced visibility (curves, fog).
Important Fact: If visibility is practically zero, the maximum speed must not exceed 50 km/h.
Sensation of speed and reduction
The brain gets used to speed ("speed adaptation"), which can deceive us into thinking we are going slower than we actually are.
- Solution: Check the speedometer frequently.
- How to reduce speed: Warn others using the brake light or your arm (palm facing down, moving it up and down) and do it smoothly to avoid rear-end collisions.
3. Times and Distances (Key Exam Concepts)
These three concepts often cause confusion. It is essential to distinguish them clearly:
A. Reaction Time
The time that elapses from when the driver sees an obstacle until they start to respond (e.g., hitting the brake).
- Average duration: Between 0.5 and 1 second (under normal conditions).
- Factors that increase it: Fatigue, alcohol, drugs, distractions.
- Remember: During this time, the motorcycle continues to move forward (Reaction Distance).
B. Braking Distance
The distance traveled from the moment we apply the brakes until the motorcycle comes to a complete stop.
- Depends on: Speed (increases drastically at higher speeds), the condition of the brakes, suspension, and road grip.
Environmental factors affecting braking:
| Condition | Effect on braking distance |
|---|---|
| Rain / Wet ground | The distance doubles (x2). |
| Ice / Snow | The distance can increase up to 10 times (x10). |
C. Stopping Distance (or Total Stopping Distance)
The sum of the two previous distances.
Formula: Reaction Distance + Braking Distance = Stopping Distance.
4. Visibility: To see and be seen
The main risk on a motorcycle is not being seen.
- Lighting: Always ride with the low beam (dipped beam) light on.
- Equipment: Use light colors on your helmet and clothing, and reflective stickers.
- Blind spots: Mirrors have blind zones. If you are going to move laterally, make sure you are seen and, if necessary, turn your head slightly to check the blind spot.
- Focus: Look far ahead to anticipate. Do not look right in front of your front wheel.
5. Riding on Downhill Slopes
When descending a mountain pass or a long slope:
- Do not exceed the maximum speed.
- Use engine braking: Ride in a low gear.
- Do not overuse the brakes: If we brake constantly, the brakes heat up and lose effectiveness (known as the fading effect).
