30.11. Which of the identification signs is installed on vehicles driven by deaf or hearing-impaired drivers?
UAЯкий із розпізнавальних знаків встановлюється на транспортних засобах, якими керують глухі або глухонімі водії?
This is an exam question from the Traffic Rules of Ukraine concerning road safety and mutual understanding among road users. Identification signs on vehicles help other drivers take into account special driving conditions in advance, especially in situations where sound signals are often relied upon (warnings, signals from other cars, special vehicle sirens). Such markings reduce the risk of misunderstandings and make traffic more predictable.
The question tests knowledge of the section of the traffic rules regarding identification signs, specifically item 30.3 (b) of the Traffic Rules of Ukraine. For vehicles driven by deaf or hard-of-hearing drivers, there is a separate sign "Deaf driver" (a yellow circle with three black dots), which is installed at the front and rear. This is the correct answer for the theoretical exam, as it is directly defined by the traffic rules for this category of drivers.
Other options in the ticket may look similar in their "special" purpose, but have different applications. The "Driver with a disability" sign, according to item 30.3 (g), is used to indicate vehicles driven by drivers with disabilities or transporting such persons, and should not be confused with the special sign for deaf/hard-of-hearing drivers. The "Doctor" sign, according to item 30.3 (zh), generally refers to vehicles belonging to doctor drivers (with their consent), and therefore does not relate to the situation of hearing impairment.
Clause 30.3 b) (identification mark "Deaf driver")
On vehicles (front and rear) driven by deaf or hard-of-hearing drivers, the identification mark "Deaf driver" is installed — a yellow circle with a diameter of 160 mm with three black circles inside, each with a diameter of 40 mm, arranged at the corners of an imaginary equilateral triangle with its vertex pointing downward.
Clause 30.3 g) (identification mark "Driver with a disability")
On vehicles driven by drivers with disabilities, or which transport such drivers or passengers, the identification mark "Driver with a disability" is installed.
Clause 30.3 zh) (identification mark "Doctor")
On vehicles belonging to doctor drivers (with their consent), the identification mark "Doctor" may be installed.
That is, the correct answer is "The first one.", considering that according to the definition of the Traffic Rules, it is the identification mark "Deaf driver" (clause 30.3 b) that is installed on vehicles driven by deaf or hard-of-hearing drivers.
The Traffic Rules of Ukraine provide for specific identification signs for certain categories of drivers so that other road users can take into account the particularities of driving and communication in advance. This is especially important in situations where people usually rely on sound signals.
According to clause 30.3 (b) of the Traffic Rules, a special identification sign "Deaf driver" is installed on vehicles driven by deaf or hearing-impaired drivers. It has a clearly defined appearance: a yellow circle with three black dots inside, and is placed both at the front and rear of the vehicle. This sign clearly indicates that the driver does not perceive sound warnings.
It is important not to confuse it with the "Driver with a disability" sign. Although hearing impairment may be grounds for establishing a disability, the Traffic Rules specifically provide for the "Deaf driver" sign in such cases. Therefore, we do not choose the general disability sign or other special markings such as "Doctor", but the specific sign for deaf or hearing-impaired drivers.
Thus, the correct answer is "The first one.", since according to clause 30.3 (b) of the Traffic Rules, it is the "Deaf driver" identification sign that is installed on vehicles driven by deaf or hearing-impaired drivers.
