Which of the following statements about blind spots is true?
a) Blind spots can be checked by looking in your rear-view mirrors.
b) Large trucks have bigger blind spots than most passenger vehicles.
c) They are eliminated if you have one outside mirror on each side of the vehicle.
d) None of the above
The Correct Answer and Explanation is:
The correct answer is b) Large trucks have bigger blind spots than most passenger vehicles.
Explanation:
Blind spots are areas around a vehicle that the driver cannot see using the vehicle’s mirrors alone. Every vehicle has blind spots, but their size and location can vary depending on the vehicle’s design. To fully understand why answer b is correct and the other options are incorrect, let’s break it down:
Blind Spots and Mirrors:
While rear-view mirrors and side mirrors are essential tools for drivers, they do not provide a complete view of all areas around a vehicle. Mirrors help in reducing blind spots, but they do not eliminate them. The areas directly beside and slightly behind the vehicle often remain unseen, especially if the mirrors are not adjusted properly. Thus, it is necessary to physically turn your head and check these areas (called a shoulder check) to ensure they are clear.
- Option a) states that blind spots can be checked by looking in your rear-view mirrors. This is incorrect because the rear-view mirror shows the area directly behind the vehicle but does not cover the areas to the sides, which are the blind spots. To check these areas, drivers need to use side mirrors and turn their head to perform a shoulder check.
- Option c) suggests that blind spots are eliminated if you have one outside mirror on each side of the vehicle. This is not true either. While having side mirrors can help minimize blind spots, they do not completely eliminate them. There will always be areas, particularly to the side and rear, that are not visible through mirrors alone.
Blind Spots and Large Trucks:
Large trucks, buses, and other big commercial vehicles have much larger blind spots compared to passenger vehicles. The size and height of these vehicles make it more difficult for drivers to see smaller cars, motorcyclists, or pedestrians in areas close to the truck. This is particularly true for the areas directly in front, behind, and along the sides of large trucks.
The blind spots around a large truck are commonly referred to as “No-Zones,” and they include:
- Directly in front of the truck – Due to the height of the truck, drivers cannot see objects or smaller vehicles directly in front of their bumper.
- Directly behind the truck – The rear blind spot extends far behind the truck because of its length. Vehicles in this area are invisible to the truck driver.
- Along the sides of the truck – The blind spots on the sides of the truck can be extensive. In particular, the passenger side (right side in most countries) tends to have a larger blind spot than the driver’s side (left side).
Passenger vehicle drivers should be extra cautious when driving near large trucks and avoid lingering in their blind spots.
Conclusion:
Answer b) is correct because large trucks have significantly larger blind spots than passenger vehicles. These larger blind spots create more risk for other drivers, which is why it’s important to understand where a truck’s blind spots are and to avoid driving in those areas for extended periods.
