Drivers of electric vehicles more likely to be at fault in road traffic crashes than drivers of petrol and diesel cars

Drivers of electric vehicles (EVs) are more likely to be involved in at-fault road traffic accidents than drivers of petrol and diesel cars, a study by researchers at Lero, the Research Ireland Centre for Software, and University of Limerick reveals.
In a paper to be published in November in the journal Accident Analysis & Prevention, the Lero researchers analysed insurance claims and data from onboard sensors and revealed a number of key findings:
- Electric and hybrid drivers exhibit different behaviours than drivers of traditional vehicles.
- Electric vehicles record more at-fault claims than traditional vehicles.
- Electric vehicles are 6.7% more expensive to repair than traditional vehicles.
Lero researcher and co-director of the Centre of Emerging Risk Studies the Kemmy Business School, Dr Barry Sheehan, said EV drivers have a higher chance of experiencing an at-fault claim than drivers of cars with internal combustion engines (ICE).
“Our research finds that despite their lower average mileage than internal combustion engines, lower road exposure for EV drivers does not reduce their risk of experiencing an at-fault insurance claim. When analysing at-fault claims, we find a 4 % increase in crashes from EVs and a 6 % increase for hybrids (HYBs) compared to internal combustion engines.
“However, when tested with statistical models, hybrids do not display any further concerns of increased at-fault claim risk. These results indicate that EVs have a higher risk profile than traditional internal combustion engine vehicles.
“Our research shows drivers' driving behaviour changes significantly when switching to hybrids or EVs. These results mean EVs are more likely to experience an at-fault claim than internal combustion engines,” added Dr Sheehan, Associate Professor in Risk and Finance at UL.
Lero researcher and lead author Kevin McDonnell said their analysis of each fuel type shows that EVs and hybrids have lower average mileages than internal combustion engines.
“This suggests that internal combustion engines should have a higher probability of incurring an at-fault claim than alternate energy fuel-type vehicles. However, the claims data contradicts this assumption by providing evidence of increased at-fault claim occurrences in EVs through predictive modelling and risk analysis,” he added.
Lero’s Professor Finbarr Murphy, Executive Dean of the Kemmy Business School at UL and co-author said that, given the increased likelihood of incurring an at-fault insurance claim with less mileage, significant first-party damages, and battery costs, alternative energy vehicles are riskier and have a higher financial burden than petrol and diesel cars.
The study used telematic data from 125 million commercial fleet vehicle trips involving 14,642 vehicles recorded from January 2022 to October 2022 in the Netherlands. It also used an insurance claims dataset during the same period.

Is mó seans go mbeidh tiománaithe feithiclí leictreacha an locht i dtimpistí bóthair ná tiománaithe gluaisteáin peitril agus díosail
Is mó an seans go mbeidh baint ag tiománaithe feithiclí leictreacha (feithiclí leictreacha) le tionóiscí bóthair ar an locht ná tiománaithe gluaisteáin peitril agus díosail, nochtann staidéar a rinne taighdeoirí ag Lero, an Lárionad Bogearraí Taighde Éireann, agus Ollscoil Luimnigh.
I bpáipéar atá le foilsiú i mí na Samhna san iris Accident Analysis & Prevention, rinne taighdeoirí Lero anailís ar éilimh árachais agus sonraí ó bhraiteoirí ar bord agus nocht siad roinnt príomhthorthaí:
- Léiríonn tiománaithe leictreacha agus hibrideacha iompraíochtaí éagsúla ná tiománaithe feithiclí traidisiúnta.
- Taifeadann feithiclí leictreacha éilimh níos airde faoi locht ná feithiclí traidisiúnta.
- Tá feithiclí leictreacha 6.7% níos costasaí le deisiú ná feithiclí traidisiúnta.
Dúirt taighdeoir Lero agus comhstiúrthóir ar an Ionad Staidéir Riosca atá ag Teacht Chun Cinn i Scoil Ghnó Kemmy, an Dr Barry Sheehan, go bhfuil seans níos airde ag tiománaithe EV éileamh ar locht ná tiománaithe gluaisteáin a bhfuil innill dócháin inmheánaigh (ICE) acu.
“D'aimsigh ár dtaighde, in ainneoin go bhfuil meánmhílte níos ísle acu ná na hinnill dócháin inmheánaigh, nach laghdaítear an baol a bhaineann le héileamh árachais faoi locht a bheith faoi lé bóithre níos ísle do thiománaithe EV. Nuair a dhéantar anailís ar éilimh faoi locht, aimsímid méadú 4 % ar thuairteanna ó feithiclí leictreacha agus méadú 6 % do hibridí (HYBanna) i gcomparáid le hinnill dócháin inmheánaigh.
“Mar sin féin, nuair a dhéantar tástáil orthu le samhlacha staitistiúla, ní léiríonn hibridí aon imní eile maidir le riosca méadaithe éileamh faoi locht. Léiríonn na torthaí seo go bhfuil próifíl riosca níos airde ag feithiclí leictreacha ná mar atá ag feithiclí innill dócháin inmheánaigh traidisiúnta.
“Léiríonn ár dtaighde go n-athraíonn iompar tiomána tiománaithe go suntasach nuair a aistrítear go hibridí nó go feithiclí leictreacha. Ciallaíonn na torthaí seo gur dóichí go mbeidh éileamh ar an locht ar feithiclí leictreacha ná ar innill dócháin inmheánaigh,” a dúirt an Dr Sheehan, Ollamh Comhlach le Riosca agus Airgeadas in Ollscoil Luimnigh.
Dúirt taighdeoir Lero agus an t-údar luaidhe Kevin McDonnell go léiríonn a n-anailís ar gach cineál breosla go bhfuil meánmhílte níos ísle ag feithiclí leictreacha agus hibridí ná innill dócháin inmheánaigh.
“Tugann sé seo le tuiscint gur chóir go mbeadh dóchúlacht níos airde ag innill dócháin inmheánaigh éileamh ar locht a thabhú ná mar a bheadh ag feithiclí breosla de chineál malartach fuinnimh. Mar sin féin, tá sonraí na n-éileamh ag teacht salach ar an toimhde seo trí fhianaise a sholáthar go bhfuil méadú tagtha ar líon na n-éileamh ar locht in feithiclí leictreacha tríshamhaltú thuarthach agus anailís riosca,” a dúirt sé.
Dúirt an tOllamh Finbarr Murphy le Lero, Déan Feidhmiúcháin Scoil Ghnó Kemmy in UL agus comhúdar, i bhfianaise an dóchúlacht mhéadaithe go dtabhófar éileamh árachais faoi locht le níos lú míleáiste, damáistí suntasacha céadpháirtí, agus costais cheallraí, feithiclí fuinnimh malartacha atá níos rioscaí agus tá ualach airgeadais níos airde orthu ná gluaisteáin pheitril agus díosail.
Bhain an staidéar úsáid as sonraí teileamaitice ó 125 milliún turas feithiclí cabhlaigh tráchtála lenar bhain 14,642 feithicil a taifeadadh ó Eanáir 2022 go Deireadh Fómhair 2022 san Ísiltír. Bhain sé úsáid freisin as tacar sonraí éileamh árachais le linn na tréimhse céanna.
