Katowice has an extensive network of freeways, roads and streets, totaling over 1,120&nbsp;km in length.<ref>{{Cite web |title=MSZ-KIIP Miejski System Zarządzania – Katowicka Infrastruktura Informacji Przestrzennej – Mapa akustyczna |url=https://emapa.katowice.eu/mszkiip/geoportal-obslugi-obywatela/mapa-akustyczna?start=3 |access-date=2022-08-03 |website=emapa.katowice.eu}}</ref> The well-developed network supports over 200,000 cars registered in Katowice, and 49 percent of commuters that drive alone, a high share compared to other major cities in Poland.<ref name=":2" /> Several freeways in Katowice are among the busiest in Poland: [[Expressway S86 (Poland)|expressway S86]] between [[Sosnowiec]] and Katowice's city center and [[A4 autostrada (Poland)|highway A4]] between Murckowska and Mikołowska interchanges both see over 100,000 cars passing each day.

Katowice has a ring around its city center, consisting of highway A4, Murckowska freeway, [[Drogowa Trasa Średnicowa]] (a freeway-style road connecting downtowns of cities in the Katowice urban area) that partly goes in a tunnel underground and Bocheńskiego road. Many of the roads and freeways in Katowice expand radially from the city center and replaced old local roads.

==== Main roads ====
[[European route E40]] passes through Katowice as [[A4 autostrada (Poland)|highway A4]]. It enters the city from Chorzów and continues eastward, with three lanes in each direction on the main road and two to three lanes in parallel access roads. It meets Bocheńskiego road and continues towards Mikołowska interchange, which is one of the only [[Interchange (road)|combination interchanges]] in Poland and the main exit towards the city center. After that interchange, the highway loses its access roads due to lack of space in the dense urban area and continues east with four lanes in each direction. Access roads appear again (only on the south side, though) after around 500 meters and there is an exit towards Francuska Street. After another 1.5 kilometer, access roads appear again on the north side, too, and there is a tight exit towards Pułaskiego Street. The highway then runs into Murckowska interchange, before exiting the city.

[[National roads in Poland#List of national roads|National road 79]] (DK79) enters Katowice from [[Chorzów]] and separates the [[Silesian Park]] and [[Osiedle Tysiąclecia]] in Katowice. It then merges with Drogowa Trasa Średnicowa (DTŚ) at the junction with Bocheńskiego road and Złota Street. It continues with DTŚ through the Katowice city center and descents into a tunnel under the Rondo roundabout. It then emerges overground again, right before an interchange with DK86. The road continues eastward as a freeway with exits towards [[Zawodzie, Katowice|Zawodzie]] and [[Szopienice-Burowiec|Szopienice]] neighborhoods for several more kilometers, before entering [[Mysłowice]] and becoming a standard-access road.

[[National roads in Poland#List of national roads|National road 81]] (DK81) enters Katowice from [[Mikołów]] and runs through the southern residential neighborhoods as an arterial road with two lanes in each direction, named [[Tadeusz Kościuszko|Kościuszki]] Street. In the Brynów neighborhood, Kościuszki Street continues towards Katowice's city center while NR 81 turns east, to run through the forest towards the interchange with DK86.

[[National roads in Poland#List of national roads|National road 86]] (DK86) enters Katowice from [[Sosnowiec]] as expressway S86 up until Roździeńskiego interchange where it meets DK79 and loses its expressway status. It then continues south as Murckowska freeway east of the city center. It meets highway A4 and then passes by [[Giszowiec]] neighborhood and continues through the woods southward, with exits towards [[Murcki]] neighborhood (from which it gets its name) and [[Kostuchna]]. It bypasses Murcki from the east and continues south towards [[Tychy]].

==== Tempo 30 Zone ====
In 2015, Katowice designated most of its city center as a {{Convert|30|km/h|mph|abbr=in}} zone, in an effort to curb traffic fatalities and crashes. Within 3 years of operation, the number of accidents dropped by 41 percent, including 37 percent drop in accidents involving pedestrians and cyclists. The accidents are also less severe: there was a 55 percent drop in injured pedestrians and cyclists.<ref>{{Cite web |title=Strefa tempo 30 |url=https://katowice.eu/dla-mieszka%C5%84ca/transport-w-mie%C5%9Bcie/strefa-tempo-30 |access-date=2022-08-03 |website=katowice.eu}}</ref>
