The speed limit on A10 east of A10/A4 interchange nr Amsterdam has confusing signage and an unposted speed limit change. Approaching the interchange is a 100kph sign followed immediately by a 70kph variable sign. Either the distance between the signs needs to be increased or the 100 sign removed. Very shortly after passing the variable sign (before the interchange) the speed limit returns to (for trucks) 80 - unknown for cars. There is no sign for this change.
