How to distinguish between one-way and two-way roads?

It depends on the presence of one-way road traffic signs. Two-way roads have two or more lanes and lack one-way road traffic signs. One-way roads typically have only one lane and are marked with one-way road traffic signs. A two-way road consists of a single carriageway with two opposing lanes of traffic, while a one-way road permits vehicles to travel in only one direction, often featuring multiple lanes.
When I first started driving, I was particularly confused about distinguishing between one-way and two-way streets, especially as a beginner when it was easy to mix them up. Practical experience taught me: one-way streets have clear signage, such as large roadside signs with arrows pointing in only one direction, along with red prohibition signs indicating no entry; two-way streets, on the other hand, usually have bidirectional arrow signs or double lane lines separating the middle of the road. In the city center, where streets are narrow and crowded, one-way streets are common to ease congestion, with all vehicles moving in the same direction; suburban roads are mostly two-way, allowing smooth bidirectional traffic flow. I remember the first time I accidentally entered a one-way street and my navigation alarm went off—it was quite a scare. Now, before driving, I make it a habit to glance at the road signs to confirm the direction and avoid risks. Using map apps can also help with reminders, but visual observation is the most reliable.
From years of driving experience, identifying one-way and two-way streets is simple: One-way streets often have clear signage, such as white rectangular signs with a single arrow and prohibition symbols, and the road width only accommodates one line of traffic. Two-way streets typically have bidirectional lanes separated by a yellow line in the middle, with no restriction signs. In cities, one-way streets are concentrated in commercial and residential areas, while two-way streets are common on main roads and highways. A reminder for beginners: don’t rely solely on navigation; observe the traffic situation more. If all vehicles are moving in the same direction, or there are no-parking signs on the roadside, it’s likely a one-way street. Entering the wrong way could result in a fine at best or a dangerous collision at worst—safety always comes first.
