In the past, when a vehicle exceeded a certain speed, a warning sound would play. What was that sound commonly called?
- Beep beep
- Ding-dong
- Alarm
See the answer
Ding-dong
In Japan, until 1986 it was mandatory to equip vehicles with a speed warning system that sounded an alarm when exceeding about 100 km/h for standard cars and about 80 km/h for kei cars. It served to alert drivers to speeding, but after a legal revision in 1986, cars with speed warnings gradually disappeared.
Why are car tires black?
- Because the additive that keeps the tire flexible is black
- Because black absorbs heat the most easily.
- Because adding carbon-based materials increases durability.
See the answer
Because adding carbon-based materials increases durability.
The main reason tires are black is the addition of carbon-based materials—especially carbon black—to improve durability. Carbon black increases a tire’s abrasion resistance, tensile strength, and aging resistance, and it also acts as a pigment, which is why tires are black.
What is the reason for keeping windshield wipers raised on snowy days?
- Even if snow piles up, you can still tell where the wipers are.
- To reduce the vehicle body's air resistance
- To prevent the wipers and windshield from freezing
See the answer
To prevent the wipers and windshield from freezing
The main reason for leaving windshield wipers raised on snowy days is to prevent the wiper blades from freezing to the windshield. If the blades are left down when freezing conditions are expected, they can freeze to the glass surface, which may scratch the glass when the wipers are used or even damage the wiper blades themselves. Furthermore, trying to operate the wipers while they’re frozen can place excessive strain on the wiper motor. Raising the wipers in advance is therefore an effective preventative measure.

Which of the following is the recommended interval for an oil change?
- Every 1,000–2,000 km or every 1–2 months
- every 3,000–5,000 km or every 3–6 months
- Every 7,000–10,000 km or every 10 months to 1 year
See the answer
every 3,000–5,000 km or every 3–6 months
In general, the recommended interval for engine oil changes is every 3,000–5,000 km or every 3–6 months. However, for newer cars or those using synthetic oil, this interval can exceed 10,000 km. It is always important to follow the manufacturer’s recommended service intervals. However,
What color cars have the lowest accident rate?
- Black, blue tones
- White, silver tones
- Red, yellow tones
See the answer
White, silver tones
According to several studies, white and silver are the car colors with the lowest accident rates. Because white and silver stand out very well both during the day and at night, they are considered safer as they make the vehicle’s presence more noticeable to other drivers. In particular, their high visibility at night is cited as one reason for the reduced accident rate.
What are the disadvantages of low rolling resistance (fuel-efficient) tires?
- Reduced grip on wet road surfaces
- short lifespan
- The weight is heavy.
See the answer
Reduced grip on wet road surfaces
Low rolling resistance tires are designed to reduce rolling resistance, but as a result, they are known to have decreased grip performance on wet roads. Reduced grip can lead to longer braking distances and may also affect cornering performance. However, tire technology is advancing, and not all low rolling resistance tires have this issue, so it is important to check the balance of performance when making a purchase.
Which of the following is the correct way to close the hood?
- Gently close it in and softly push it in
- Push the lever to open the hood
- Release it from about 20 cm above and let it drop naturally.
See the answer
Release it from about 20 cm above and let it drop naturally.
It makes a loud noise and may seem rough, but in fact, the recommended method is to let it close using the momentum of free fall. You might think it's better to gently lower it and press it shut, but pressing it can risk deforming the hood.
