The Role of Automobiles in Prohibition


During the Prohibition era in the United States, which lasted from 1920 to 1933, the government made alcohol illegal. But people still wanted to drink, so they found ways to get it anyway. Cars played a big role in this. People used them to smuggle alcohol from places where it was still legal to places where it wasn’t. Let’s take a closer look at how cars became such a crucial part of this time in history and how they made it tough for the police to catch the people breaking the law.

Origins of Prohibition

Origins of Prohibition

The origins of Prohibition can be traced back to the temperance movement, which highlighted the detrimental effects of alcohol on society. Advocates of the movement believed that banning alcohol would enhance public morals, reduce crime, and increase productivity. Their efforts led to the ratification of the 18th Amendment in 1920, which made the production and sale of alcohol illegal in the United States.

However, Prohibition had several unintended consequences. One major issue was the significant loss of tax revenue from alcohol sales, which states had previously depended on. This financial void drove many individuals to engage in bootlegging—the illegal production and distribution of alcohol. Bootleggers became central figures of the Prohibition era, employing various methods to evade law enforcement.

The rise of bootlegging also spurred the growth of organized crime. Notorious figures like Al Capone exploited the illegal alcohol trade to build extensive criminal networks. These operations often involved smuggling schemes that required fast cars to evade capture.

The need for high-speed, agile vehicles in these illicit activities indirectly contributed to the creation of NASCAR, as bootleggers modified their cars for optimal performance. 

Rise of Bootlegging

Rise of Bootlegging

During Prohibition, smuggling routes evolved significantly due to the mobility provided by automobiles. Bootleggers used cars to transport illegal liquor quickly and covertly.

This demand for speed and secrecy not only facilitated smuggling operations but also contributed to the origins of NASCAR.

NASCAR, the National Association for Stock Car Auto Racing, is an American auto racing sanctioning and operating company. Founded in 1948, it is best known for stock car racing events. The organization oversees numerous racing series, the most prominent being the NASCAR Cup Series, which features high-speed races on various tracks, including ovals, road courses, and superspeedways.

Smuggling Routes Evolution

Amid expanding smuggling routes, Michiganders exploited the varying alcohol laws in the Toledo-Detroit-Windsor triangle by using the Interurban Electric Railway to transport illegal liquor. Michigan had already banned alcohol in 1918, two years before national Prohibition took effect, leading to the evolution of creative smuggling methods to bypass these laws. Residents smuggled alcohol from Ohio, cleverly hiding it in fake Bibles or stashing it in covert compartments within vehicles.

The rise of bootlegging saw the Detroit-Windsor-Toledo triangle become a significant hotspot for illegal alcohol trade. Organized crime groups like the Purple Gang capitalized on the situation, using automobiles to move large quantities of illegal alcohol. Initially, the lack of police cars made it easier for these criminals to operate unchallenged.

Speed and Secrecy

As bootleggers exploited evolving smuggling routes, they relied on fast cars and expert driving to transport illegal whiskey, outmaneuvering law enforcement with speed and secrecy. These drivers weren’t just any motorists; they were skilled professionals who often modified their vehicles to enhance performance and capacity.

To maintain their operations efficiently, bootleggers implemented several key modifications to their cars:

Engine Upgrades: High-performance engines were crucial for the speed needed to evade capture.

Enhanced Suspension: Improved suspension allowed cars to carry heavy loads of illegal whiskey without sacrificing speed.

Driving Techniques: Bootleggers honed their skills on dark back roads, often driving with headlights off to avoid detection.

Evading Law Enforcement

The growth of the automotive industry in the 1910s provided bootleggers with faster, more agile cars, often resembling race cars in performance. To evade capture, rum-runners honed their driving skills to maneuver on various terrains. 

With these fast cars, bootleggers could transport their illicit goods more efficiently, making it challenging for law enforcement to keep up. 


Moonshiner ingeniously used hidden compartments and false bottoms in their cars to smuggle illegal alcohol past law enforcement officers. By integrating secret storage areas into their vehicles, they could effectively conceal their contraband. These compartments were often so well-crafted that even a thorough search by an officer mightn’t uncover them. You’d be amazed at the lengths they went to for concealment, utilizing every inch of space in their cars.

In addition to hidden compartments, bootleggers also cleverly disguised their vehicles to look like regular, everyday automobiles, blending seamlessly into traffic to avoid suspicion. This disguise was essential for evading law enforcement, who were constantly on the lookout for suspicious activity during Prohibition.

The mobility of cars also played a significant role in their evasion tactics. Bootleggers could quickly change routes to avoid roadblocks, using the speed and agility of their vehicles to stay one step ahead of the authorities. On dark back roads and in rural areas, this ability to swiftly alter their course provided them with a significant advantage in smuggling operations.

Speakeasies and Hidden Bars

As automobiles facilitated the smuggling of alcohol, hidden bars known as speakeasies became the go-to spots for those seeking to enjoy a forbidden drink. These clandestine establishments flourished during Prohibition, providing a secret haven for people to socialize and indulge in illicit alcohol. Speakeasies thrived in major cities, with New York City alone boasting an estimated 30,000 to 100,000 hidden bars.

To maintain secrecy and avoid detection by law enforcement, speakeasies often employed elaborate methods:

Hidden Entrances: Many speakeasies were tucked away behind unassuming storefronts, requiring visitors to navigate through basements, back alleys, or even secret passageways.

Passwords: Entry often required a password or secret knock, ensuring that only trusted patrons gained access.

Soundproofing: To prevent the sounds of revelry from attracting attention, some speakeasies invested in soundproofing their walls.

Bribes: Many speakeasy operators paid off police and local officials to turn a blind eye to their activities.

This era of hidden bars not only provided an escape from the restrictions of Prohibition but also contributed to the cultural and social fabric of cities like New York, embedding the concept of the speakeasy deep into American folklore.

Impact on Auto Industry

A pivotal moment came in 1932 with the introduction of the Ford V-8 engine. This engine revolutionized bootlegging cars, making them faster and more powerful than police vehicles. With this new engine, bootleggers gained a significant edge, enabling them to transport illegal alcohol swiftly and evade capture more effectively.

The automotive industry growth in the 1910s laid the groundwork for these advancements. As car manufacturing ramped up, so did the availability of fast, reliable vehicles. This growth indirectly supported the success of bootlegging activities, as there was a greater selection of cars to modify and use for illegal purposes.
