# Europe's Highest Speed Limits and Unlimited Roads Comparing speed regulations in Poland, Bulgaria, and Germany with the US. - **Source:** [SlashGear](https://www.slashgear.com) - **Published:** 2026-07-14 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/da07e20c-e0fc-4607-b899-b756a63b6147 ## US vs. European Speed Limit Comparison While the US tops at 85 mph (137 km/h) in Texas, Poland and Bulgaria allow 87 mph (140 km/h) on highways. Europe's road infrastructure and traffic management enable higher limits. However, strict enforcement prevents widespread speeding, maintaining discipline on these fast lanes. ## Poland's Strict Speed Enforcement Poland enforces 50 km/h urban limits and 120 km/h on divided roads, with autostradas at 140 km/h. Heavy fines and frequent checks deter violations. A 2025 proposal to reduce limits to 130 km/h was rejected in parliament, preserving the country's high-speed highway network. ## Bulgaria's Flexible Highway Rules Bulgaria permits 87 mph on modern highways with emergency lanes. A 2025 legislative attempt to lower limits for certain vehicles to 130 km/h failed. The country stands out for having one of Europe's most adaptable speed policies, balancing mobility and safety effectively. ## Europe's Two Unlimited Speed Zones The Isle of Man and Germany's Autobahn are Europe's only unlimited-speed public roads. Isle of Man police focus on safety reminders rather than speed checks. On the Autobahn, while 130 km/h is recommended, 2025 data shows average speeds around 125 km/h despite no upper limit. ## How the Autobahn Functions Over half of Autobahn's 8,077-mile network has no speed limit. Yet 80% of drivers adhere to the 130 km/h recommendation, with 2025 averages at 125 km/h. German highways remain among the world's safest high-speed infrastructures, combining engineering excellence with driver discipline. ## Balancing Speed and Road Safety Europe's varied speed policies reflect infrastructure quality and driver education. Poland/Bulgaria's high limits and Germany's unlimited sections offer valuable transportation case studies. Safety is maintained through rigorous enforcement and a culture of responsible driving, proving speed and security can coexist. ## Sources covering this story - https://www.slashgear.com/2211157/fastest-speed-limit-sign-in-europe/ — --- _Summary written by Brifing from the original reporting.
