A vehicle-ramming attack, also known as a vehicle as a weapon or VAW attack,[1] is an assault in which a perpetrator deliberately
rams a
vehicle into a building, people,[2][3] or another vehicle. According to
Stratfor Global Intelligence analysts, this attack represents a relatively new militant tactic that could prove more difficult to prevent than
suicide bombings.[4]
Deliberate vehicle-ramming into a crowd of people is a tactic used by
terrorists,[5] becoming a major terrorist tactic in the 2010s because it requires little skill to perpetrate, cars and trucks are widely available, and it has the potential to cause significant casualties.[6][7][8] Deliberate vehicle-ramming has also been carried out in the course of other types of
crimes,[9] including
road rage incidents.[10][11] Deliberate vehicle-ramming incidents have also sometimes been ascribed to the driver's
psychiatric disorder.[12][a]
Vehicles have also been used by attackers to breach buildings with locked gates, before detonating explosives, as in the
Saint-Quentin-Fallavier attack.[13]
Causes and motives
Ease
According to the U.S.
Federal Bureau of Investigation, the tactic has gained popularity because "Vehicle ramming offers terrorists with limited access to explosives or weapons an opportunity to conduct a homeland attack with minimal prior training or experience."[2] Vehicles are as easy to acquire as knives, but unlike knives, which may arouse suspicion if found in one's possession, vehicles are essential for daily life, and the capability of vehicles to cause casualties if used aggressively is underestimated.[14]
Vehicle attacks can be carried out by
lone-wolf terrorists who are inspired by an ideology but who are not working within a specific political movement or group.[16] Writing for The Daily Beast, Jacob Siegel suggests that the perpetrator of
the 2014 Couture-Rouleau attack may be "the kind of terrorist the West could be seeing a lot more of in the future", a kind that he describes, following Brian Jenkins of the
Rand Corporation, as "stray dogs", rather than
lone wolves, characterizing them as "misfits" who are "moved from seething anger to spontaneous deadly action" by exposure to
Islamist propaganda.[17] A 2014 propaganda video by
ISIL encouraged French sympathizers to use cars to run down civilians.[18]
According to
Clint Watts, of the
Foreign Policy Research Institute, where he is a senior fellow and expert on terrorism, the older model where members of groups like
al-Qaeda would "plan and train together before going to carry out an attack, became defunct around 2005", due to increased surveillance by Western security agencies.[17] Watts says that
Anwar al-Awlaki, the American-born al-Qaeda
imam, as a key figure in this shift, addressing English-speakers in their language and urging them to "Do your own terrorism and stay in place."[17]
Jamie Bartlett, who heads the Violence and Extremism Program at
Demos, a British think tank, explains that "the internet in the last few years has both increased the possibilities and the likelihood of lone-wolf terrorism", supplying isolated individuals with ideological motivation and technique.[19] For authorities in Western countries, the difficulty is that even in a case like that of the perpetrator of the 2014 Couture-Rouleau attack, where Canadian police had identified the attacker, taken away his passport, and were working with his family and community to steer him away from
jihad, vehicle attacks can be hard to prevent because, "it's very difficult to know exactly what an individual is planning to do before a crime is committed. We cannot arrest someone for thinking radical thoughts; it's not a crime in Canada."[19][20]
According to
Stratfor, the American global intelligence firm, "while not thus far as deadly as
suicide bombing", this tactic could prove more difficult to prevent. No single group has claimed responsibility for the incidents.[4][clarification needed] Experts see a saving grace in the ignorance and incompetence of most lone-wolf terrorists, who often manage to murder very few people.[19]
Protest encounters
Vehicular ramming has sometimes been advocated to attack
protesters who block public roadways in the United States. Two police officers were suspended and fired in January and June 2016, respectively, for tweeting such advice about
Black Lives Matter rallies, which have sometimes been broken up by cars.
North Dakota state legislator
Keith Kempenich tried and failed to pass a law granting civil immunity to drivers who accidentally hit activists after his mother-in-law was stopped by
Dakota Access Pipeline protesters, and
Tennessee Senator
Bill Ketron did likewise after a man hit an
anti-Trump group. Similar legislation has been introduced in
Florida and
Texas.[21]
Protective measures against vehicle attacks are known as hostile vehicle mitigation. This involves reducing the risk posed by vehicle as a weapon attacks through a mixture of measures. Visibly this often includes physical barriers, but also includes other measures such as deterrence, staff training, traffic management, and incident response planning.[22]
Security bollards are credited with minimizing damage and casualties in the
2007 Glasgow Airport attack,[23][24] and with preventing ramming in the
2014 Alon Shvut stabbing attack, leading the assailant to abandon his car and attack pedestrians waiting at a bus stop with a knife, after his effort to run them over was thwarted.[25] However, Berlin's police chief, Klaus Kandt, argued that bollards would not have prevented the
2016 Berlin truck attack, and that the required security measures would be "varied, complex, and far from a panacea".[26]
On 23 October 2014, the US
National Institute of Building Sciences updated its Building Design Guideline on Crash- and Attack-Resistant Models of
bollards, a guideline written to help professionals design bollards to protect facilities from vehicle operators, "who plan or carry out acts of property destruction, incite terrorism, or cause the deaths of civilian, industrial or military populations".[27] The
American Bar Association recommends bollards as effective protection against car-ramming attacks.[28]
In January 2018, it was announced by the then
mayor of New York City,
Bill de Blasio, that the city planned to install 1,500 steel street barriers to prevent vehicle attacks. This came after the city's two vehicle-ramming attacks in 2017 killed nine people.[29]
Münster has been planning to install security bollards in public areas in response to vehicle-ramming attacks in European cities, including the Berlin attack.[30] While only selected locations can be protected this way, tight bends and restricted-width streets may also prevent a large vehicle getting speed before reaching a barrier.[31]
Modern
Internet-connected
drive-by-wire cars can potentially be
hacked remotely and used for such attacks. To demonstrate the severity of this type of attack, 2015 hackers remotely carjacked a Jeep from 10 miles away and drove it into a ditch.[32][33] Measures for
cybersecurity of automobiles to prevent such attacks are often criticized as being insufficient.[citation needed]
In Toronto, older transit buses and sanitation vehicles are used as anti-ramming barricades, providing a more benign public experience.[34]

Personal Violence" in The American Psychiatric Publishing Textbook of Forensic Psychiatry (2d ed.: eds. Robert I. Simon & Liza H. Gold), pp. 551-52: "An automobile is a potentially lethal machine. Litigation involving psychiatrists has resulted when a hospitalized patient, after discharges, caused a two-person vehicle accident with death or injuries to one or more victims ... Such cases involve three different types of scenarios. One is the vehicular crash that results from the patient's medication-induced drowsiness at the wheel ... The second scenario is a true accident but is unrelated to any prescribed medication. Rather, the patient's driving is impaired by the disabling effects of mental illness [or] recent consumption of nonprescribed drugs or alcohol. The third situation is when the patient deliberately crashes into another vehicle. Neuropsychiatric conditions that can be associated with an increased risk of vehicular crash include psychotic exacerbation of schizophrenia, profound or suicidal depression, dementia, and disturbances in consciousness, such as epilepsy and narcolepsy."
