Medications that should not be taken before driving include: 1. Sedatives and sleeping pills: Phenobarbital-class drugs often have side effects such as drowsiness, fatigue, dizziness, and in large doses, can cause ataxia, temporary memory loss, and impaired consciousness, which can affect a driver's judgment and reaction time, leading to accidents. 2. Antihistamines: First-generation antihistamines, also known as sedating antihistamines, including diphenhydramine and promethazine, can induce varying degrees of dizziness, vertigo, fatigue, attention deficits, and slowed reactions. Overdosing can worsen these effects, making them unsuitable for drivers. 3. Antispasmodics: Atropine, scopolamine hydrobromide, and belladonna tablets may cause dizziness, blurred vision, and attention deficits. 4. Antipsychotics: Both typical and atypical antipsychotics have sedative effects and can cause dizziness, blurred vision, fatigue, drowsiness, attention deficits, and slowed reactions. Overdosing exacerbates these effects, making them unsuitable for drivers. 5. Cough suppressants: Drugs like pentoxyverine and dextromethorphan can cause dizziness, headaches, drowsiness, and fatigue, making them unsuitable for use while driving. 6. Analgesics: Morphine, codeine, and pethidine can cause dizziness, vertigo, fatigue, drowsiness, attention deficits, and pupil constriction, impairing driving ability. 7. Ulcer medications: Omeprazole can cause dizziness, tinnitus, blurred vision, drowsiness, and numbness in the legs; cimetidine, ranitidine, and famotidine can cause dizziness, fatigue, and drowsiness, all of which impair driving ability. 8. Anti-angina medications: Propranolol and mexiletine can cause headaches, blurred vision, tinnitus, and hypotension. High doses may lead to bradycardia, heart block, or even fainting, requiring caution while driving. 9. Anti-angina medications: Propranolol and mexiletine can cause headaches, blurred vision, tinnitus, and hypotension. High doses may lead to bradycardia, heart block, or even fainting, requiring caution while driving. 10. Blood pressure and diabetes medications: Unlike drugs affecting the nervous system, antihypertensives like propranolol, reserpine, and nifedipine can cause drowsiness, headaches, dizziness, and hypotension, affecting driving safety. All diabetes medications carry a risk of hypoglycemia, especially insulin and sulfonylureas. Taking them on an empty stomach increases risks. Improper use can lead to drug-induced hypoglycemia, causing palpitations, dizziness, sweating, and collapse, all hazardous for driving.

I remember one time I drove after taking cold medicine containing diphenhydramine, which made me dizzy and nearly caused me to sideswipe a guardrail. Since then, I've been extra careful: many medications should never be taken before driving, such as painkillers like codeine or fentanyl, which can cause severe drowsiness; antihistamines like chlorpheniramine have similar effects, slowing reaction times; even sleeping pills or antidepressants can impair judgment. If everyday cold medicine is labeled 'not suitable for driving after use,' it's best to stay off the road. The risks of driving under the influence of medication are too high—accidents are more likely, and you could face fines or license checks. I recommend checking the medication instructions and waiting until the effects have completely worn off before driving. Safety comes first, protecting both yourself and others. It's also a good idea to keep some non-drowsy alternatives on hand.

When it comes to driving under the influence of medication, from a health perspective, I must remind everyone that it is very dangerous. Common problematic medications include sedatives such as Valium or sleeping pills, which depress the central nervous system and slow down hand and foot reactions; antihistamines in cold medicines can make people drowsy; even blood pressure medications sometimes cause dizziness. The key is to pay attention to the warnings on drug labels and avoid driving during the peak effect period of the medication. I recommend consulting a professional before taking any medication and choosing non-drowsy alternatives; if medication is necessary, wait at least a few hours to allow the body to metabolize the drug components. Safe driving is not only about personal safety but also involves the well-being of others—don’t risk major consequences for minor gains. Developing the habit of reading medication instructions can help prevent accidents.

After having children, I became extra cautious about driving safety. Driving after taking medication is absolutely unacceptable, especially cold and cough medicines or sleep aids, such as those containing diphenhydramine, which can impair your focus. Every time I'm responsible for picking up or dropping off my kids, I make sure I haven't taken any such medications. If I feel unwell, I ask family members for help or take a taxi. Avoiding driving under the influence of medication is a basic responsibility to ensure the safety of the whole family. Simply checking the ingredients of the medication is enough—don't take unnecessary risks.

What is the Function of a Torque Converter?

The functions of a torque converter: 1. Transmit torque: The engine's torque is transmitted through the driving element of the torque converter, then via ATF to the driven element of the torque converter, and finally to the transmission. 2. Continuously variable transmission: The torque converter can achieve stepless changes in speed and torque within a certain range. 3. Automatic clutch: Since the torque converter uses ATF to transmit power, the engine will not stall when the brake pedal is pressed, which is equivalent to the clutch disengaging. The torque converter is a type of hydraulic transmission component, consisting of a pump impeller, turbine, and guide wheel. The pump impeller is connected to the driving shaft and converts the mechanical energy input from the driving shaft into the kinetic energy and pressure head of the fluid through centrifugal force for the turbine to perform work. The turbine is connected to the driven shaft and outputs the energy contained in the fluid's kinetic energy and pressure head through the driven shaft.

How to Turn Off Audi Auto Start-Stop?

Audi auto start-stop can be turned off mainly through the following two methods: 1. The operation is relatively simple and does not require any changes to the vehicle. Each time you start the vehicle, after entering and starting the car, since the Audi auto start-stop function is enabled by default, you need to locate the auto start-stop switch near the center console and turn it off. After turning it off, the dashboard will display a prompt indicating that the auto start-stop function is unavailable. However, if you restart the ignition switch, you will need to repeat this step to ensure the system remains off. 2. The operation is more professional and requires the use of a dedicated diagnostic tool. Insert the diagnostic tool into the vehicle's OBD port, establish communication with the vehicle, and access the address code 09 for the central electrical equipment control unit. Find the "Allow Entry" function, enter "20113" to confirm, then input channel number "34", read and note the original value, add "30" to the original value, and click save. After performing this operation, the system will default to the off state upon the next vehicle start. If you need to use the auto start-stop function, simply press the switch to turn it on.

How to Set Up the Volkswagen Locking Horn Activation?

Volkswagen's locking horn activation cannot be set up by oneself; it is achieved by modifying the ECU programming. In the factory settings of some Volkswagen models, the locking confirmation sound feature is disabled by default, meaning the horn does not sound when the doors are locked. This makes it difficult for many owners to determine whether the doors have been successfully locked or opened. After enabling this function, hearing the horn sound upon locking provides assurance that the doors are securely locked. The Volkswagen Bora is a compact car under FAW-Volkswagen. Taking the 2021 Bora 200TSI DSG Comfort Intelligent Connect Edition as an example, its body dimensions are 4663mm in length, 1815mm in width, and 1462mm in height, with a wheelbase of 2688mm. The vehicle features a 4-door, 5-seat sedan structure, a fuel tank capacity of 50 liters, and a curb weight of 1320kg.
