However, many countries, especially low- and middle-income countries (LMIC), lack country-specific VSL estimates. To address this, value transfer is often used, where VSL estimates from other countries are adapted to local situations to estimate the VSL in the countries with no VSL estimates. This paper presents new guidance for VSL value transfer in the context of road safety.Method: A unit value transfer approach is applied, which implies that a base VSL is determined and used to estimate the VSL in other countries. We collected VSL estimates from 32 countries worldwide to determine base VSLs for both high-income countries (HIC) and LMIC. According to the literature, the VSL is strongly correlated with income per capita. Therefore, income elasticities from the literature are applied to account for the impact of per capita income on the VSL.Results:  The resulting VSL transfer functions are VSL = 0.404*(Y/5,726)1.2 for LMIC and VSL = 3.206*(Y/42,087)0.8 for HIC, where VSL is the VSL in million USD and Y is the Gross National Income per capita (USD, 2020 prices). The VSL ranges from approximately 22,000 USD to 1.1 million USD in LMIC and from 1.2 million USD to 4.8 million USD in HIC.Conclusions: We recommend applying this VSL transfer approach for cost-benefit analysis and road crash costing in countries lacking appropriate country-specific VSL. Moreover, this study highlights that, despite the growing interest in LMIC in research on VSL, the number of studies in these countries is still limited, emphasizing the need for more VSL studies. Finally, developing transfer functions for non-fatal injuries is recommended, whi
